Cramping? Miscarriage?

I'm currently 4 weeks and I'm having slight cramping it almost feels like pinching. Is this normal? Also I have pressure near the bottom of my stomach and feels like I need to go to the bathroom but I dont. I'm super scared but I'm trying not to stress. I have no spotting at all just the pinch feeling. This is my first pregnancy and I wanna prevent miscarriage as much as possible. PLEASE HELP!!!!😭🥺
