I am currently taking birth control but it isn't working right now because of my antibiotics for acne. I had sex a few days ago and have been bleeding some since then and it's mixed with a white discharge. I already had my period almost 2 and a half weeks ago. I have been getting headaches for a little over a week and a half. We used a condom also. But I am worried because my breast stsrted to feel sore a little today and they have gotten bigger. I am 18. thoughts please?
