So I usually have a 5 day period. Last month my period lasted only 4 days and was extremely light on the last day, whereas my 4th day is a pretty moderate flow day. And now this month my period lasted 7 days. It was light and over to my knowledge the 5th day as normal, but the 6th day I had bright red blood and it was a little more than light but I wouldn't say moderate. It didn't stop until mid day the 7th day. I was just wondering if that could have been related to pregnancy. My boyfriend and I have unprotected sex on my period and he doesn't pull out. When I am not on my period he always pulls out. I am not on birth control. What does this mean? I am normally very very regular.
