and I'm kinda freaking out! AF is usually on CD27 or 28 and CD29 has now come and gone. I'm thinking I might have just O'd later than I thought and that could be what is causing AF to be a little late. AF is very rarely late

We were using withdrawl but that has always worked for us in the past. POAS this afternoon and it was negative but not sure how accurate it was since it wasn't FMU.
This would really be rough timing for another baby. Lilah is still so little and she just started sleeping through the night a few months ago. She also had digestion troubles that we just got under control about 6 weeks ago. Plus she was my second c-section. Plus we are in a major transition right now.
I'm sure AF will show up in the morning but this wait is killing me! I can say this much, if I'm not pg right now, we def will be abstaining during fertile times from now on lol!
