“My boyfriend and I had unprotected sex and he didn’t pull out. This was yesterday and my stomach has been hurting a lot since I woke up this morning. Could I possibly be pregnant or could it just be from the sex or neither?”
It is unlikely that you would be feeling any affects from this unprotected sexual encounter. However, if this is not the first time that you had unprotected sex, you might have gotten pregnant or contacted a sexually transmitted infection from having a previous unprotected sexual encounter.
Please go see your health care provider to be certain that you are not pregnant, get tested for STIs and talk about birth control options.
Hope this helps.
