Hi, so my boyfriend and I have been going out for a while and about 2 months ago we decided to have sex (March 26th), we used a condom as i'm not yet on any birth control. We did it again on March 31st except this time we didn't use a condom - stupidly - but we did oral at the end so i know he didn't ejaculate 'in me'... I started my period a week later on the 7th/8th of April for the usual 5 days but now I'm about 2 weeks late... I've heard cases where women have had sex before their periods, had their period but still ended up pregnant. Any chance I could be pregnant?
