I had unprotected sex twice a day from July 4th to the 9th. He did not pull out any of those times. I’m also not on birth control. I got my period two days ago and it ended tonight. Normally my periods are very heavy and last for 6 days. The first 4 days are very heavy and then the next two days are light. I bled light both the two days I had my period and heavy for about one hour the first day. The blood was also a light brown. (I know that’s normally old blood). I’m wondering why it lasted only 2 days instead of 5-6 and why the bleeding was so light. Has anyone had this happen and do you think it could’ve been because the unprotected sex?
