Cramps in my sides & lower stomach. was sexually active the 26th of this month. no conform was used, but he pulled out. could i be pregnant?

Anything possible: I would see your doctor to determine if you are pregnant or not... this might also be the onset of your period. When does it usually come around?

Maybe (not): Unprotected sexual activity is best way to get pregnant. Therefore, yes, you could be pregnant from unprotected sex on 26th (just 4d ago) even if he pulled out (very unreliable form of birth control). However, it's unlikely that pregnancy from 26th would cause your pain. Perhaps pregnancy from prior unprotected sex. Or sexually transmitted infection from unprotected sex. Or simple bladder infectio

Pregnancy: Unfortunately, Any time you have unprotected sex, especially when using poor birth control such as the "pull out" method, you are at risk of becoming pregnant. It would be early for cramping, but check a pregnancy test if you miss your period, and see the dr. now if your cramps are persisting. Good luck.

Yes: Anytime you have unprotected sex (without a condom), and you are not using a reliable form of birth control, there is a possibility of pregnancy. Pulling out is not a reliable method to prevent pregnancy. If you are having symptoms this soon after intercourse a STD is more likely the cause, although you could potentially be pregnant too.
