Pain 😖

Lynda • Proud Mommy Of 2 ❤
So according to glow I'm 5 weeks 6 days. This is my second pregnancy and I'm in pain and I'm thinking its to early to feel this pain. Sometimes it hurts to lay on my stomach at night. Now when I lean forward or bend over my uterus hurts. I know the baby isn't that big but can I be hurting my baby or is it just my uterus expanding for the baby. It's so uncomfortable to the point that I'm unbuttoning my pants when I sit down. Is this normal ? What's going on ? Should I call my doctor?
