My husband and I have been ttc for 2 months. We had sex every other day through ovulation. My last period was July 2-5th and I am always on time. I am a week late no sign on AF with a few possible pregnancy symptoms such as sensitive nipples, heighten sense of smell, major bloat, gas, hiccups, cramping (minimal)and a lot of white slight yellow CM. And rising BBT. I've taken 4 tests all BFN. I'm not sure what to think? HELP! It's my very first time trying any advice will be so helpful.
