Almost every other day and sometimes everyday for the month of June and July I have been having unprotected sex with my boy friend who is the father of our two year old daughter. In June when I got my period we even had sex right before I started it and on the last two days of my period. On Friday July 6th we had sex in the morning and by 10pm that night I had started my period. It started really lightly which is normal but then by Sunday turned into a regular sort of heavy period. During my period I had no cramps. My period lasted until July 10th. Today July 13th I woke up with extremely horrible stomach pain. I also have been feeling tired and craving ice cream, milk shakes and candy since we started having sex in June. Before that I never really ate sweets. I also have been extra moody and can cry over just about anything. Could I be pregnant or is this normal behavior?

Honestly I didn't need to read your whole question, just the first sentence.

If you have had sex, unprotected or not you could be pregnant.

No-one can tell you what is normal behavior for you. I crave chocolate and strange combinations of food when I have PMS, others only when they are pregnant. Only way to know for sure is to take a test.
