I had my youngest child 16 months ago and have never had a PP AF.
I've consistently tested once a week for months and months now.
I tested last Friday, 7/13/12 and it was negative on a FRER.
I tested this morning, 7/20/12 on a FRER and it was VERY positive, yay!
I noted EWCM on 7/10 but had had it a few weeks / days before then as well.
Anyone want to take a shot?
