I'm 19 and this month I've had my period like always which is good. it lasted a week like usual but approximately two weeks after my period I had some irregular vaginal bleeding that lasted also a week but it didn't completely go away. this morning I woke up and was bleeding again like my period had started. what's going on?! some other things are, I'm really stressed out, I'm very exhausted and hungry all the time. this might be too much information but I'm gunna say it anyways but I am bisexual and have only been with a girl in the last little bit n I'm kinda convinced she scratched me internally bcuz wen we were done I started bleeding a little bit n that wen it started after that happened. please help
