Hi, Me and my DH have been ttc since February. I came of Cerazette but have not had AF since so not too sure what my CD are. I got some OPK tests and tested from the 3rd of April due to increased CM. I had a positive OPK's on 5th and 6th April, so plently of and a very DH! I have a bit of cramping in the last couple of days but not much else but since i'm not sure if or when AF is due how will I know when to test!!! Sorry if this seems like a daft question, I'm aching for a ! My damn hormones got me.
