Yeah, every month when I was TTC and I have TTC a lot in the last 8 years. I have had 4 m/c and I always had a positive HPT. I feel you are just wanting it so much that you were having psychosomatic symptoms. Just go with that and avoid the extra emotional anguish that goes with having a m/c, struggling to TTC is hard enough on you.
Good luck for next month (and wish me good luck too).
