Twinges in both ovaries?

I just came off BCP june 8th 2011 me and my husband want to try for a baby. We had sex around the 17th for about a week after that i had twinges in both ovaries. I could really feel it if i sat directly on my butt or flopped down on it when sitting down it was also kind of tender to push on that area. It never really hurt just a little tender. Could it be my body going back to normal? My husband wants to bet money im pregnant i've never been preg. so i dont know what to expect just not sure if its something i should worry about i was on the pill for about 7 years.
