maybe someone out there can help me. I got my period Jan 25 it lasts about 5-7 days for it to completely go away. That being said today makes 13 days since I got my period. I just went to the bathroom and a gush of blood very watered down came out with a bit of tissue. This has never happened to me in all my years of having a vagina. I’m 29 I weigh 140 and I’ve had my period since I was 13. I did have sex a few times after my period went away last week. Any suggestions on what it can be?
