I'm thinking of retesting again, but nervous. Had two BFN since being 16 days late. But it's been two weeks since. :/ Not having too many symptoms besides a bit more going to the RR, a bit of discharge, cravings, and a bit of heart burn. I feel nervous it being another BFN and crying. >.< If no AF next week, I'm making an appointment with my doctor. I'm so nervous to be so heart broken.
