Possible MC

I went to the ER tonight because I was bleeding. It started with absolutely no cramps. I got my first pregnancy test on January 6th. I have been tracking my period for 8 months now and the thing that is so weird my period was supposed to start today. I technically haven’t had a missed period yet but have had 16 positive pregnancy tests over the past couple weeks.

The thought was that I am about 4-5weeks so super early. They did an ultrasound and couldn’t see anything obviously. They took a pee test and a blood test. The pee test was negative and the blood test he said my hcg levels were low at 31. (I don’t know what normal is?)

Anyways obviously my husband and I are devastated. I decided to take a test when I got home and it was still super positive. I go back and have my hcg levels checked in a couple days.

I’m trying to have hope everything will work out but the doctor made it seem not good. This is my first pregnancy and my husband and I were really excited and already told many people.
