Pregnant with ectopic risk

Hello all, I am turning 21 next week and just found out I was pregnant yesterday. I had severe pain and cramping for days and began bleeding so I went into the emergency room. I have a hemorrhaging cyst and PID right now. The doctors originally thought I was having an ectopic pregnancy but since I am 4 weeks along, they cannot find the location of the pregnancy. I’ve had PID (from unknown causes) three times already and have severe scarring, so they said there’s a likely chance when they are able to find the location of the pregnancy it may be ectopic. They are testing my HCG levels ever 48 hours to see if maybe the PID is causing a miscarriage, or if I continue to be pregnant. Because ectopic pregnancy termination requires a shot or surgery, I have to wait 2-3 weeks until they can see where it’s at. If the pregnancy is viable, they say that I can choose a termination method then if I wish. I’m hoping it’s a miscarriage or that it’s ectopic so I don’t have to choose. But if I do, what method do y’all recommend? What worked best and was the least painful? I’m thinking about surgical aspiration if I must get an abortion, but I know I may have to wait until 7/8 weeks for it to be most effective. I don’t know if I can wait that long with this inside me. I am a full time graduate student and I have been an absolute mess so I want it taken care of as soon as possible. What are your experiences with a medical or surgical abortion?
