💊 Contraception & Reproductive Life Planning

Most contraception questions are really contraindication questions. Learn who cannot have estrogen and the rest follows.

🚨 Who must not have estrogen

Estrogen increases clotting. Every contraindication below is either a clot risk or a hormone-sensitive cancer.

  • Smoker over 35 - the classic exam stem
  • History of DVT, PE or a clotting disorder
  • Migraine with aura — stroke risk
  • Uncontrolled hypertension
  • Known or suspected pregnancy
  • Breast cancer; active liver disease
  • Under 6 weeks postpartum, or breastfeeding early on

⭐ ACHES — report immediately

Abdominal pain · Chest pain · Headache (severe) · Eye problems · Severe leg pain

Every one of those is a possible clot. This mnemonic is worth more marks than the method list.

📊 The methods, by how well they work

MethodTypical useKey teaching
Implant / IUD>99%Most effective; nothing to remember. Copper IUD also works as emergency contraception
Sterilization>99%Consider permanent; counsel accordingly
Injection (Depo)~96%Every 12 weeks; bone density loss — calcium, vitamin D, weight-bearing exercise
Combined pill / patch / ring~93%Same time daily; estrogen rules above
Condom~87%The ONLY method that prevents STIs
Diaphragm~83%Refit after childbirth or big weight change; leave in 6 h after
Withdrawal / fertility awareness~77–80%Least reliable

✅ The teaching point students miss

An IUD or implant is more effective than sterilization on paper — but only condoms protect against infection. A woman with an IUD and a new partner still needs condoms. That is dual protection.

🧠 Missed pill rules

  • One pill missed — take it as soon as remembered, even if two in one day. No backup needed
  • Two or more missed — take the most recent, continue the pack, and use backup for 7 days
  • Vomiting or diarrhea counts as a missed dose
  • Antibiotics and anticonvulsants can reduce effectiveness — use backup

🩸 The cycle underneath it all

A 28-day cycle in two halves, with ovulation in the middle.

 Follicular (days 1–14)Luteal (days 15–28)
HormoneFSH, then estrogenLH, then progesterone
OvaryFollicle maturesCorpus luteum forms
UterusLining rebuildsLining becomes secretory, ready to implant

Ovulation is triggered by the LH surge, about day 14. Menstruation begins about 14 days AFTER ovulation - that half is fixed, and cycle length varies in the first half.

🌡️ Signs of ovulation

  • Cervical mucus becomes clear, stretchy and slippery — like raw egg white (spinnbarkeit)
  • Basal body temperature dips, then rises about 0.5°F and stays up
  • Mittelschmerz — one-sided mid-cycle pain

The temperature rise confirms ovulation after it has happened, so it is poor for avoiding pregnancy but useful for achieving it.

🎯 NCLEX traps

  • Smoker over 35 = no estrogen
  • ACHES = report immediately
  • Only condoms prevent STIs
  • Depo = bone density, so calcium and weight-bearing exercise
  • Luteal phase is fixed at 14 days; the follicular phase varies
  • Breastfeeding is not reliable contraception

🗺️ The five method families

Start every conversation with one question:

“Would you like to become pregnant in the next year?”

Counselling is person-centred and noncoercive. The client chooses the method — or chooses no method. You make the choice informed, you do not steer it.

FamilyWhat it isThe hook
Fertility awarenessTrack fertile days; avoid or use a barrier in the windowNeeds consistent monitoring and predictable cycles
BarrierCondom, diaphragm, cap, sponge, spermicideUsed at each act
HormonalPill, patch, ring, injection, implantAdherence and safety screening drive the teaching
IntrauterineCopper or levonorgestrel IUDLong-acting and reversible
PermanentVasectomy or tubal surgeryTreat as permanent — confirm certainty and consent

🌿 Natural methods — and the one that is not contraception

🤝 LAM — all three or it does not count

  • No return of menses
  • Fully or nearly fully breastfeeding, day and night
  • Less than 6 months postpartum

Reassess immediately when any one criterion changes. Miss one and the method has stopped working.

↩️ Withdrawal

Requires correct timing every single time, is less effective with typical use than most alternatives, and gives no STI protection.

🚩 Postcoital douching

This is not contraception.

Sperm reach the cervix within seconds. Douching does not prevent pregnancy and must never replace emergency contraception.

🌡️ Fertility awareness — the four signs

SignHow it is measuredWhat trips students up
CalendarStandard Days Method is built for cycles 26–32 daysIrregular cycles make it unreliable
Basal body tempBefore rising, same time daily, with a thermometerThe rise happens after ovulation; illness and poor sleep skew it
Cervical mucusSlippery, clear, stretchy — like raw egg whiteThis is the classic exam answer for “how do I know I am fertile”
LH testingUrine kit detects the pre-ovulatory LH surgePredicts ovulation; does not confirm it happened

Fertility awareness = mucus + temperature + calendar. If an answer choice is not one of those three — feeling hot, mood swings, breast sensitivity — it is a distractor.

🛡️ Barrier and hormonal timing

🎈 Condoms

  • New condom for every actnever reuse either type
  • Water- or silicone-based lubricant only. Oil weakens latex
  • The internal condom goes in before any penile contact — pre-ejaculate carries sperm and STIs. It can be placed up to 8 hours ahead

⏱️ The numbers

  • Diaphragm — leave in 6 hours after intercourse, out within 24 hours
  • Patch — weekly × 3, then a patch-free week
  • Ring — monthly: 3 weeks in, 1 week out
  • Depo — every 12 weeks IM
  • Implant3 years, inner upper arm

🦴 Depo deposits leave your bones

Black-box warning for bone mineral density loss → calcium, vitamin D, weight-bearing exercise. Return of fertility can take 9–10 months.

Progestin-only methods all share one headline side effect: irregular bleeding, heaviest early on.

🔩 IUDs — strings, timing, and who cannot have one

CopperLevonorgestrel
Durationup to 10 years3–8 years by product
Hormonenoneprogestin
Bleedingheavier or longer at firstirregular early, then often lighter
Alsomost effective emergency contraceptionnot used with current breast cancer

🧵 Teach the strings

Check monthly, after each period. Missing, longer, or shorter strings can mean expulsion or perforation — call the provider and use backup.

Placed more than 7 days after bleeding began? Backup for 7 days.

🚨 Do not insert with

  • Known pregnancy
  • Current purulent cervicitis
  • Current chlamydial or gonococcal infection

Seek care for severe pelvic pain, fever, foul discharge, very heavy bleeding, changed strings, or a positive pregnancy test.

Two myths exams love: IUDs are not restricted to people who have given birth, and fertility returns almost immediately after removal.

✂ Permanent methods

Vasectomy

  • Blocks the vas deferens
  • Does not reduce testosterone, erection, or desire
  • Not immediately effective — backup until semen analysis confirms it

Tubal surgery

  • Occludes or removes the fallopian tubes
  • Effective immediately
  • Pregnancy is rare — if it happens, evaluate for ectopic

Tubal ligation is a roadblock, not a shutdown. Ovulation, hormones, and periods all continue — the egg is simply reabsorbed. Sperm can no longer reach the ovum because the tubes are blocked.

⏰ Emergency contraception

OptionWindowKey points
Copper IUDwithin 5 daysMost effective. Works immediately and keeps working as ongoing contraception
Ulipristal 30 mgwithin 5 daysBetter than LNG late in the window. Wait 5 days before starting hormonal contraception, then backup 7 days
Levonorgestrel 1.5 mgASAP, within 5 daysBetter the sooner it is taken. Start or resume hormonal contraception immediately, then backup 7 days

EC does not end an established pregnancy and gives no STI protection. No bleeding within 3 weeks → pregnancy test.
