So last cycle was my first of using progesterone suppositories. Ever since stopping breastfeeding my son in October I have been getting peak opk om CD 18 and ovulating on either CD 19 or 20. But I've been having regular 29 day cycles. That is why my doctor prescribed the progesterone. Last cycle I ended up not pregnant and stopped the progesterone and it took a couple days to get my period. But I'm on CD 12 right now and got a really close to positive opk. Has anyone who's taken progesterone for a short LP end up having their cycle regulate and start ovulating closer to the 14 or 15 day mark again ? Before having my son I ovulated around that time and regular 29 day cycles.
