Ectopic Pregnancy or Viable Pregnancy? Confused!

La

I found I was pregnant on 1/18. Here comes Tuesday 1/22 and I go to the restroom and wipe and there was a ton of brown blood on the toilet paper. Went to the ER cause I freaked out. Got to the ER and that brown turned to red. Had a transvaginal ultrasound done and blood work. Levels came back at 800 HCG & ER doctor said it’s an ectopic pregnancy, he could see the sac in my right tube but no baby. Started feeling pain and symptoms of an ectopic pregnancy and thought my tube burst so I went back the next day. Levels were between 800-900 and was told I was having a missed abortion/miscarriage. I passed 2 clots, they weren’t big but maybe about the size of the top of your thumb. Got in with my OBGYN on Thursday did another ultrasound and more blood work but this time for my liver to see if it’s affecting my liver if it really is an ectopic pregnancy. My OBGYN said it’s very very low chance of me having an ectopic pregnancy and that this could be a viable pregnancy but they can’t see anything just yet. My doctor also said that bleeding and clots can be normal in early pregnancy. I read online that you can’t usually see a sac until your levels are like 1000-2000. I go back Tuesday to my OBGYN for another ultrasound and tests. I’m pretty nervous and praying that there is a baby and that I didn’t miscarry or that it didn’t implant in the wrong place. Have any of you ever experienced anything like this??
