Chest/Heart pain 5 weeks 2 days

Kal

Hi mommas, I’m currently 5 weeks and 2 days today, and for the last couple of days I’ve been having immense chest/heart pains. I’ve been putting off going to the emergency room because I wouldn’t classify it as a dire emergency. Today i also had very sharp stabbing smack dab in the middle of my uterus that lasted about 5 minutes which I figured was stretching. First pregnancy and I can’t find much info online so I was wondering if this was normal? Or is it something I need to have looked at? I do not have a primary doctor (I usually just go to urgent cares if need be) I do have an appointment with a new OB at 8 weeks but do you think I should/would be allowed to do a walk in appointment to have it checked out?
