TW: MC, Ectopic or pregnant again

Vent/ has anyone had similar situation?

So I had a miscarriage starting 7/23. I got it confirmed by the drs, they did an ultrasound and said everything has passed. my levels were originally 200+. The next hcg confirmed it with an immediate drop to 40s, followed by a drop to 17 2 days later. I was told to wait 10 days to retest and it should be 0. My next test was 60s then 2 days later (Thursday) it was 100+. My regular ob thinks I got lucky and got pregnant right away. My RE specialist says she scared it’s ectopic and I’ll need to go to er. Im getting more bloodwork today but im just so nervous. If it’s ectopic they want me to do methotrexate shot (which I wouldn’t have a choice) but I really don’t want to. And on the flip side if I’m pregnant again I would be so great full but obviously scared for another MC. 😪
