having symptoms but getting BFN

Melissa
Alright ladies, having some symptoms but still getting a BFN. According to my app my husband and I had sex a few days before ovulation, on my ovulation day, as well as a few days after. AF was due four days ago. I have had sore breasts for over a week now, they have grown in size and are very sensitive and heavy. I usually get sore breaths with AF but never this bad. I am also feeling very bloated. I have taken three PT and all are BFN. I have ocassional cramps and twinges. My discharge is a watery white and sometimes so watery i think AF has arrived so I run to the bathroom only to see there is no blood. Help me! I don't want to get my hopes up just yet. What do you ladies think I should do?
