Postpartum cycle

Ima • Classical American Mom

So I've been pregnant 5 times 2 live birth 2 early miscarriages, one due in less than a week. So far my cycle has started 28 days after delivery or start of miscarriage. I got pregnant 6 weeks postpartum and quickly miscarriages so these are definitely real cycles. I've tried Lam twice (first time I slipped up and had 1 feed 4 hour apart husband was supposed to bring baby to me to feed but lost track of time and baby and I slept through 1 feed at 27 days and my cycle started within 12 hours, so that one might have been on me, but the next time I was crazy careful again and never missed any feeds cycle still started at 28 days), but it doesn't work for me😅. Any temping tips with a newborn?
