Really bad poop pains?? Tmi

JšŸ’ž
I literally just found out I'm pregnant yesterday and I'm already worried about every little thing haha. I've been having really bad stomach pains like I need to poop, I did poop but not very much and still have some pains. I'm only like 3 weeks 6 days. It's not like period cramping or anything. But is this normal?
