Is It Possible To Be Pregnant Again After An Abortion, While On Petogen, If I M Experiencing Bloating And Breast Pain And My Period Is Late?

I had an abortion 2 months back. I was then given petogen birth control. I had sex with my boyfriend after two months without a condom and my next date has not come yet . I started getting bloated and having breast pains. I m worried if I might be pregnant again. Is that possible?
