6 week cramping

Hey guys! I just hit 6 weeks today and have pretty consistently been having cramping odd and on ever since I found out I was pregnant. I was having sharp, shooting pains (mostly on my right side, but some on my left here and there) for the first week or so, but haven’t had them in a few days. I do have endometriosis so i’m not sure if that could be the cause of my cramping? Now i’m sitting on my lunch break and just had a sharp, shooting pain in my shoulder that lasted and few seconds and went away. I know that could be a sign of an ectopic pregnancy and i’ve just been freaking out ever since I found out. I’ve been mildly crampy today as well. What do you guys think? My first appointment isn’t until next Thursday.
