ultrasound/ bleeding

Reyna 🌈👶🏻2018 🌈👶🏻2021

so I went to the ER again due to bleeding but this time was more red ans a small clog like when ur on you period. when I got the the ER they did an ultrasound and didn't not see a fetal pole, or a yolk sac and fetus... they did another HCG test ans the levels are still rising but the Dr said the most likely is a non viable pregnancy or a miscarriage my bleeding stopped when I was at the ER and that was around 10:40am and I was released by 3pm. the dr said that I would be bleeding for the next 3 to week but since yesterday when I was release I have not bleed I only have like a brown light discharge... has this happen to anyone? my other dr from OBGYN asked me and told me that this is most likely an Ectopic pregnancy which they have not confirmed it because they don't see anything growing in my ovaries and she asked me if I was willing to get a biopsy and find out why this happened and why they are not able to find the fetus. but there is a risk that if I that ans there a baby in there it could kill it. I just don't know what to do im not even having any severe cramping like they said I would. I really wanted this baby and have been trying for 9 yrs.
