Hello! Before I start, I'd like to say that my periods have been irregular in the past 4-5 months, but the last 2 months I get it around the same time....except for this month. I got my period April 7th. It's always very heavy the first day and then the 2nd and 3rd day it's super light and ends up going away before the 4th day. So I had it until the 9th. I think we had sex on he 12th or 13th. We didn't use a condom. Now it's may 11th and I still haven't gotten my period. Do you think I'm pregnant or is my cycle just off...again! ? Please help!
