Discharge

So I’ve been on BC for about 6 years now, and I’m really good about taking it. Ive been having odd symptoms for me lately, I’m 13 DPO had unprotected sex with my husband about four days before ovulation. I know that BC is suppose to prevent ovulation but I also know that’s not 100%. Anyways since then I’ve had pains in my stomach and pelvis, I’ve fainted and been light headed, I had a tinge a spotting, and most of all I have been having way more discharge than normal. I’ve been to the doc and he ran a pregnancy test on 5/6 and it was negative, I took one at home that same day and thought I saw a vvvfl, then the next day tried again and got a neg. my period should start 5/9 or 10, and I was just wondering if anyone else had heavy egg white discharge on BC?

Sorry for the long post.
