Am I crazy or chemically imbalanced??

I'm on cycle day 34 and I have had a regular 30 day cycle for the last 5 months or so, give a take a day a few months in those last 5. DH and I used an OPK this past month and I got my LH surge on April 12th. We BD the 9th, 11th, 12th, 13th, 15th, and 17th just to be sure. I know I missed the 14th but hubby needed a break, his 14 hour work days take a lot out of him so by the time he gets home, he just wants to eat then sleep and I don't blame him for that, it would be brutal for me! The first week after ovulation I had no symptoms at ALL, just lots of mild cramping at the end of that week and lotion like CM. The start of the second week though my BBs became full and tender and my nips hurt waaay more than the BBs, cramps continued with twinges in my ovaries???? < That part has me way confused (?Maybe I ovulated later than I thought and the OPK was misleading?) By the time AF was expected to arrive I had watery CM and AF type cramps. This had me running to the bathroom armed with a tampon but every time, no AF. I'm now 4 days late and utterly confused. From the beginning of the second week I have been very weepy and emotional, and prone to sudden outburts of near rage over little things I would normally let go. I took it as PMS being magnified but when AF didn't rear her ugly head I started to wonder. I've been through several tests and all have been negative, all using FMU and following instructions EXACTLY. Ladies I am so utterly confused, does anyone have any advice for me at all?
