I was 5 weeks and that's what was happening to me before I found out it was because i was pregnant! It felt so bad. It rly is normal. It's bc your body is starting to prepare your body for the rest of your pregnancy
I did, but I had a subchorionic hemorrhage and also needed to be put on progesterone. so maybe you should get looked at but its also normal, your uterus is starting to stretch out and move up to make room for baby.
