There is a certain amount of cramping/pain to be involved. Follow your instincts. Call the doctor if you're worried. With my first I called a lot. They are there to answer questions.

It's my first baby and everything scares me because idk what is normal and what is not😭 thanks ! @mylittleprincess

as long as there's no bleeding yes. your uterus is starting to grow and push other things around.
