I am ttc baby #2 and still breastfeeding my 13 month old. I just started getting AF again in June so this was the official month of ttc. I used opk and tracked my bbt and CM and pinpointed my ovulation day 7/8. I usually have 28-30 day cycles which makes me 2-4 days late at this point. I am not sure if it takes a while for AF to regulate postpartum?? Has any one on here ttc while breastfeeding? Does it mess with your cycle at all? Any advice would help. As of this morning with fmu i got a bfn.
