Patient Script

Who I Am

I am 32, a primary school teacher, and I had a baby 6 weeks ago.

What Brings Me In

I want to discuss contraception — I’m worried about getting pregnant again now that I’m back to life with a newborn.

My Story

I had a normal vaginal delivery 6 weeks ago and my baby has been exclusively breastfeeding until about 2 weeks ago, when I started giving occasional formula during daytime visits to family. Since delivery I’ve had no heavy bleeding, just some light spotting for the first 2 weeks. I had a small episode of breast tenderness and a lump at 3 weeks that my GP said was likely blocked ducts and it settled with heat and expressing. I’ve been feeling tired but that’s expected with a newborn. I’m worried because I’ve read online that you can get pregnant even when breastfeeding, and I’d like something reliable because I’m back at work part-time in 6 weeks.

I don’t want anything that will interfere with breastfeeding if possible, and I’d prefer a method I don’t have to think about every day. I am open to an IUD or implant but I’m a little anxious about having a device inserted. I also had a really bad migraine years ago when I was a teenager but it was just one episode and I haven’t had headaches like that since — I don’t have visual changes or aura when I get headaches now.

My Medical Background

• Past medical history: uncomplicated pregnancy and vaginal delivery; one teenage migraine episode (no aura) years ago
• Medications: multivitamin, infant vitamin D for the baby (none for me currently)
• Allergies: none known
• Social: drinks alcohol rarely (one glass on special occasions), used to smoke socially in my twenties but quit 4 years ago, lives with partner who helps with baby care
• Family history: mother had breast cancer at 58; maternal aunt had a DVT after surgery decades ago (I don’t know details)

What I Think & Worry About

• I think breastfeeding might protect me from pregnancy, but I’m not sure how reliable that is.
• I’m worried about getting pregnant again too soon and not being able to care for two babies.
• I hope for something that won’t reduce my milk supply and that is safe while breastfeeding.

If You Ask Me About Other Symptoms...

• Vaginal bleeding: "Only light spotting for about two weeks after the birth, nothing heavy now."
• Breast problems: "Lump and tenderness at 3 weeks that settled with expressing; no fever now."
• Headaches: "I used to have a bad migraine once when I was a teen, but I haven’t had anything like that since."
• Leg pain / swelling / chest pain: "No shortness of breath, no calf pain, no chest tightness."
• Mood: "Some nights I feel low and exhausted but I haven’t had any thoughts of harming myself or the baby."
• Sexual activity: "We’ve had sex a couple of times since 4 weeks postpartum with condoms; partner had a vasectomy talked about in jest but hasn’t had it."
• Contraceptive history: "Used the combined pill years ago and stopped because I forgot to take it; had no side effects then."

Diagnosis

Primary diagnosis:

• Postpartum contraception counseling — 6 weeks postpartum, breastfeeding (mostly), seeking an effective, breastfeeding‑compatible method.

Supporting evidence:

• Patient is 6 weeks postpartum and sexually active; negative pregnancy test rules out current pregnancy; exclusive/mostly breastfeeding reduces but does not eliminate ovulation risk; desires effective contraception.

Differential diagnoses / considerations:

• Lactational amenorrhea method (LAM) as temporary method: may be applicable if exclusive breastfeeding and amenorrhoeic, but patient is no longer exclusively breastfeeding and plans return to work — hence LAM is less reliable.
• Early return of ovulation/postpartum pregnancy: earliest ovulation can occur before first menses; pregnancy ruled out by negative pregnancy test but further contraception needed.
• Contraceptive contraindications: migraine with aura — patient has history of a single migraine without aura (not a contraindication to combined methods), and family history of DVT in an aunt is not a direct contraindication but personal VTE risk should be explored.

Management

• Immediate steps:
  • Confirm current breastfeeding status and goals for breastfeeding duration.
  • Offer and discuss progestin-only methods as first-line while breastfeeding: progestin-only pill (POP), subdermal implant, levonorgestrel IUD, or depot medroxyprogesterone injection — explain efficacy, advantages, side effects.
  • Offer copper IUD or levonorgestrel IUS insertion now if patient desires long-acting reversible contraception and uterus involution is adequate; discuss risks of insertion at 6 weeks postpartum and obtain informed consent.
  • Explain that combined oral contraceptives are generally not preferred while breastfeeding and are usually deferred until breastfeeding is well-established (commonly 6 months) or until lactation is complete, and early postpartum use carries a higher VTE risk.
  • Perform a pregnancy test (already negative) immediately before inserting an IUD or initiating a LARC.
  • If choosing progestin-only pill, provide prescription and review missed-pill guidance; if choosing implant/IUD, arrange same-day or soon appointment for insertion and provide information about follow-up and signs of complications.
  • Discuss non-hormonal options (copper IUD, condoms) and permanent methods if she desires definitive contraception in the future.
• Safety and follow-up:
  • Advise to seek review for fever, heavy bleeding, severe pelvic pain after IUD insertion, or any signs of VTE (leg swelling/pain, sudden dyspnea) though her immediate risk is low.
  • Arrange a follow-up visit in 4–6 weeks after starting chosen method to assess tolerance and breastfeeding concerns.
  • Document counseling, chosen method, and consent.

Key Learning Points

• Progestin-only methods (POP, implant, levonorgestrel IUD, DMPA) are generally preferred for breastfeeding women in the early postpartum period because they do not reduce milk production and have a favourable safety profile.

• The lactational amenorrhea method (LAM) provides effective contraception only when strict criteria are met (exclusive breastfeeding, amenorrhea, infant <6 months); partial breastfeeding or return to work reduces its reliability.

• Long-acting reversible contraception (IUD/implant) can be initiated in the early postpartum period with appropriate assessment; combined estrogen-containing contraceptives are usually avoided early postpartum and in breastfeeding women until lactation is established due to concerns about VTE risk and milk supply.
