On birth control. Sex no condom 1week ago pulled out but can I b pregnant from precum or anything he didntfeel I have had cramps in my stomach and pain?

Chat with your doc. If you are properly on birth control pills you should not become pregnant. Cramps and pain in your stomach can be due to other things and you should speak with your doctor. As you probably know when you have unprotected sex there are certain diseases that you can get even if you are taking birth control pills.
