I'm 16 years old. On march 8th 2013 I had sex with my clothing on. I was on my period during that. On April 6th of this month I got my period so I don't think I'm pregnant. More recently I had sex during my period on te 8 th of this month. Now it's the 13 th. I visited my gynecologist recently like 2 days ago. My hormones are in balance and no uti or infections. Anyways my breast are changing. A lot. Since I ended my period about 3 or 4 days ago its not pre menstrual symptoms. My breasts get sharp pains in them occasionally more in te nipples. They areolas are darkened and bigger. There is a vein like ring around them as well. I just don't know what could be happening. This started about 3-4 weeks ago and still hasn't ended. Actually it started after the first incident with sex with clothes on. And has gotten worse after the actual intercourse. Help please!
