This is my second postpartum cycle. Still breastfeeding on demand. Only had an 8 day LP last cycle. Ovulated on CD 20 last cycle. Seems like I'm ovulating on CD 19 this time (had a positive last night, too). Hopefully, my cycle is getting closer to normal! We dealt with infertility (diminished ovarian reserve) for almost three years before our son came along. We're hoping for a second miracle!
