Since December I have been getting my period 3 times a month and been spotting in between so I had been bleeding practically the whole month I also start bleeding after sexual intercourse and my period have been longer than 7 days the longest has been 13 days I really don't know what to do I am 17 and I have gone to check if I have stds and I don't

Have you changed your birth control or started a new kind? Something similar happened to me when I changed my birth control. I went back to the gyno and she said that I probably had a high dosage for my body so she changed it to something less extreme because my hormones were all out of whack which caused the month long spotting.

No I don't use birth control
