Hey ladies I had a few questions... I am sexually active and the last time I had sex was July 13th, I was on my period and my period ended July 16th. Then I had an extremely light/spotting “period” the 28th through the 1st. Now I’m having brown/red discharge on and off. I took a pregnancy test a few days ago and it was negative. What could be going on?

Edit: So I unlogged the 28th through the 1st thing as a period, and Glow says that it’s my ovulating time. But this didn’t seem very normal. Anyway, now it says that I am 4 days late to my period. (I usually start a few days after Glow says I will)

UPDATE: So now Glow says that I am 8 days late. My nipples are hurting and for me this isn’t regular. With my periods my entire breast area hurts, not just my nipples. I’m also having diarrhea. Idk if that’s any constellation. I am also trying to get over a sinus infection that I’ve had for about a month now. So I’m not sure what is going on with me. I’m going to take another test tomorrow.
