I recently just had sex for the first time on Monday. My partner and I used protection, and even then I made him pull out before he came just to be safe. But since about 2 hours after intercourse, I have been experiencing pain in my lower stomach area. It feels like menstrual cramps in the uterus area. The pain is not unbearable, but sometimes unconfortable enough that I have to take a pain reliever. I am curious as to if this is normal or not, because it's been almost 4 days of pain, considering the fact it was only my first time having sex and I am 16 years old.
