So I had sex, he used condom and am taking the birth control pills for over 1 month after that two weeks passed And I got my period for 5 days, it wasnt that much.

Since that everything normal, I went to my dermatologist and she changed my pills, I started taking them this Saturday but now my vagina is swollen, my stomach is like cramping a lot and it’s a little inflated.

Am really nervous

What can it be?
