She had a baby. Then her cycle disappeared — and nobody told her what that actually meant, or when it might come back, or whether she could get pregnant again before it did. Rose McKenzie has spent over a decade helping women understand their hormones in the moments when they feel most invisible: irregular cycles, postpartum, perimenopause. And she'll tell you plainly — the postpartum body is not a mystery. It's a system coming back online. The problem is nobody's watching the data.Rose is the clinical manager at Mira and a natural family planning practitioner with more than 10 years of experience helping women use hormone tracking not just for fertility, but for whole-body health awareness. Today she joins Dr. Susan Fox for a conversation about what's actually happening to your hormones after birth — and why tracking them postpartum is one of the most informed things a new mother can do, whether she wants to conceive again, avoid conceiving, or simply understand her own body.You'll learn why your hormones don't flip back on like a light switch after birth — and what the slow train analogy actually tells us about your return to cycling, why ovulation can return as early as eight weeks postpartum even while breastfeeding — and why that matters more than whether your period has come back, what the Lactational Amenorrhea Method (LAM) actually requires — and why almost everyone gets "kicked out" of it sooner than they expect, why a positive LH surge is not confirmation of ovulation — and what progesterone has to do with it, what "cycle wonky" means and why your first one to four cycles back are not your baseline, what the teeter-totter between prolactin and the body's drive to ovulate looks like on a hormone chart, how intentionally disrupting your nursing pattern — carefully and with support — can help jump-start ovulation for those trying to conceive while still breastfeeding, why tracking postpartum hormones led to two PCOS diagnoses that conventional medicine would have missed entirely, what Mira actually measures and why an LH strip alone doesn't give you the full picture, and why Mira is data — not a diagnosis, not a treatment plan, and not a standalone method for avoiding pregnancy. This episode is for you if you've just had a baby and have no idea when your hormones will return or what "normal" even looks like right now, you're breastfeeding and want to understand whether pregnancy is actually possible for you right now, you want to conceive again and aren't sure if your body is hormonally ready, you've been assuming your period has to come back before ovulation does, you're curious about natural family planning and want to understand how hormone tracking fits into it, or you want to stop floating around postpartum and start actually knowing what your body is doing. Support your fertility journey with Preconception Plan at Health Youniversity.
