I had an M/C in October and my periods only returned in early March, but DH and I decided to try straight away and pretty much went for it the week I would be ovulating if my periods were regular. Well it's now three days before AF is due. Last weds I had two days of really odd cramping and a little bit of spotting which then stopped. Since then my boobs seem to have blown up and are very sensitive and I've had that unique rounded bloat. I've tested a few times and it's been a BFN. Is it possible these are all in my head because I want it so much or should I just wait a bit longer?
