Hi.. I Recently Had A Large Cyst Removed And The

Hi.. I recently had a large cyst removed and the doctor had to cut me like a c section cut. I know I suppose to wait a good few months before having sex but my husband and I are newlyweds and we had sex exactly one month after the surgery. I am fine walking about and everything at was from the second week after surgery. But I think I might be pregnant and it's worrying me because of my cut what do you suggest I do.?
