I am 16 years old. I started my period when i was about 9 and i have never had a regular period. My periods come once every 3 to 5 months. I have been sexually active since i was 13 years old. I don't have any knowledge of ever being pregnant if that's important. I had been having sex with one guy for about a year and i used a condom everytime. I recently stopped having sex with him about a month ago and i had my period about 2 weeks ago but today i noticed i was bleeding again its light red almost pink. Is that something i should be worried about??
