My partner and I had intercourse last March 24, 2013. After that I had my period on the 28th. Is it still possible to get pregnant in that case? I've been sleepy in the past few days and having mood swings... I'm wondering if am pregnant or what?please advise thanks.

Yes, although the flow is usually light. Wait another week or two to see if you feel the same before you buy some HPTs and start testing. Symptoms are NEVER positive evidence of pregnancy, pre-menstruation, or anything else. They merely indicate probable hormone changes.
