So I’m on the pill and am supposed to get my period tomorrow but when I wipe it’s very very very light pink. I put a tampon in and when I took it out there wasn’t a lot on it and it was brown wit maybe a little red. I had a preg blood test on Thursday and it came back negative (for other blood work they just decided to do that too). Should I be concerned about this? Also. There’s nothing on my liners
