Is it possible for me to be pregnant 3 days after ovulation?

Every month, about a week to a week and a half after my period, I feel when I ovulate. The pain only lasts a few hours and there is no remnants of pain the next day. This month is different. I ovulated on Saturday, and still feel crampy, heavy, and definitely bloated.....it is now Monday evening. My boyfriend and I have had sex everyday since my period, and even when I ovulated. Any answers will be appreciated, BTW, this would be a fourth child for me if I'm preggers.
