Hi, I lost my virginity 4days ago. We didn't use protection but he didn't ejaculate, I took the morning after pill, but I have a stomach ache/cramps. I'm really worried I'm pregnant.
It would be early for you to even be pregnant - yet.
Cramping is common in women when they first start having sex. You did things with your body that it just isn't used to.
Emergency contraceptives (and stress) can also cause stomach aches and cramps.
It is unlikely you are pregnant if you took the morning after pill within 72 hours. Hope it helps.
