Breifly: had ERPC in July, first AF Aug 20, second AF AWOL, BFN on Sunday. This morning I thought she was here but nope, only some brown discharge. Boobs very sore, and sicky feeling but I realize that this is PMS too. Cycles are very normal usually (28 days) so technically I am nearly a week late. I have 3 HPT's but feel bad wasting them...WWYD?
