Could I be pregnant?

My fiancé and I decided to go off birth control. I was off it for two weeks and we were having sex every day or every other day. I now have cramps and a lot of bloating. My breasts are a little sore, but not many other signs. I just got accepted into the credential program, so we decided that it's beSt for me to go back on birth control for a few more months so I can get through schooling. I was wondering if I could have gotten pregnant during this time. Also, if I am can I hurt the baby by going back on birth control? Thank you in advance.
