I had been on antibiotics for over a week. I ovulated on the 9th, and we had sex the 7th and 8th. Both without protection. This morning we had sex and right after i noticed light pink bleeding which later turned into a bright red. i have not been bleeding MUCH, not enough for a tampon, but it is still enough for me to have to wear a pad so i don't gross anything up. However i am not due for my period for another 9 days according to the app on my phone (which is 100% accurate so far, have been using the app for a year and never been wrong.) I'm just confused as to what this is. PLEASE HELP! I'm worried there may be something wrong medically or maybe i am just pregnant? Thank you.View Thread
