What it is
Most guidelines say wait until bleeding has stopped and any stitches or incisions have healed — usually around 4–6 weeks — but there's no magic date. Pain with first intercourse is common, especially with lactation-related vaginal dryness (low estrogen) or scar tissue. Fertility can return BEFORE the first period. Exclusive breastfeeding gives roughly 98% contraceptive protection ONLY when all three LAM criteria are met (baby under 6 months, exclusively nursing day and night, periods have not returned). Most other methods are compatible with breastfeeding; combined estrogen methods are typically delayed at least 3–6 weeks and sometimes longer while nursing.

Possible benefits
- Knowing what's normal makes it easier to say what's not (persistent pain, heavy bleeding after sex)Review sources ↓
- Choosing contraception before you need it prevents a very-close-spaced pregnancy (linked to higher risks)Review sources ↓
- Long-acting reversible contraceptives (LARCs) can be placed at the postpartum visit or even at birthReview sources ↓
Possible risks
- Very short interpregnancy intervals (<6 months) are linked to higher preterm birth risk in a next pregnancyReview sources ↓
- Combined hormonal methods too early postpartum can increase clot riskReview sources ↓
- Painful sex ignored for months becomes harder to treat — get pelvic PT if pain persists past 2–3 monthsReview sources ↓
Alternatives
- Non-hormonal: copper IUD, condoms, diaphragm, fertility awareness (with training)Review sources ↓
- Progestin-only: mini-pill, DMPA shot, progestin implant, hormonal IUD — considered safe while breastfeedingReview sources ↓
- Combined estrogen + progestin: usually delayed 3–6 weeks non-nursing, longer if nursingReview sources ↓
- Permanent: tubal ligation (can be at cesarean or postpartum) or vasectomy for partnerReview sources ↓
Current evidence
ACOG Practice Bulletin 186 on long-acting reversible contraception, CDC US Medical Eligibility Criteria for Contraceptive Use, and WHO's Medical Eligibility Criteria all address postpartum and lactation. Cochrane reviews cover LAM effectiveness.
Where the evidence is clear · where people may choose differently
For most topics, guidelines from ACOG, WHO, and other major bodies broadly agree on the core safety points (when to act in an emergency, informed-consent standards, monitoring baselines). Where reasonable people — and even guidelines — differ tends to be around thresholds (when to start or stop something), preferences (comfort, environment, support), and values (how you weigh small risks against benefits). Use the questions below to explore those pieces with your care team.

Questions to ask your care team
- ?What's a realistic timeline for resuming sex given how I gave birth?
- ?If sex still hurts at 8–12 weeks, what would you look for and where would you refer me?
- ?Which methods are compatible with breastfeeding, and which do you recommend for me?
- ?Can we plan contraception before I leave the hospital or at my first postpartum visit?
Universal questions (works for any decision)
A short BRAIN-style set you can bring to any conversation about interventions, monitoring, or care decisions.
- ?Why are you recommending this now — is it urgent, routine, or optional?
- ?What happens if we wait an hour (or longer) before deciding?
- ?What signs would tell us this is working — or that we need to change course?
- ?What are the alternatives, including doing nothing?
- ?What would you recommend if this were your family?
- ?What would change your recommendation?
