So we decided to try for DC2 about 3 weeks ago. I came off the mini pill, and within a few days had EWCM. Lots of DTD (mainly because coming off the pill means that I actually have a libido again, but that's another thread!) and 2 days ago started to get the usual AF symptoms - sore boobs, slight stomach cramps, feeling heavy etc. Had one single spot of bright red blood yesterday, and nothing else, although symptoms are still there. Ordered a stash of pg tests from e bay, and they arrived yesterday, so thought I'd give one a try 
and it was negative. I think I'm hanging to a very faint hope that there has only been one spot raher than anything resembling an AF, so maybe, just maybe...... The test would have come up positive though wouldn't it?
