So sad :( (PICTURES TMI!!)

Hey so I wanted to know if anybody ever experience bleeding in their pregnancy and blood clots similar to a light period.. ever Wednesday when I had a transvaginal ultrasound and had sex I’ve been having light bleeding and it’s not stopping! On the 23rd my hcg levels were 794.. on the 26th which was on Wednesday, it went to 4339.. I started bleeding that day.. i went back to my doctor and she did a ultrasound and said the sac was still there and sent me to get my rhogam shot.. I went to the ER and got my rhogam shot very early this morning and they checked my hcg levels and it was 9015 so they just said it was rising this morning..but it seem like it’s too high? Doctors keep telling Me to just to have pelvic rest, I’ve never bled like this before In my pregnancies, it started out as spotting to a light period like flow then when I was walking I felt this come out and had more bleeding with it but now it’s back light right now.. I’m just scared and don’t know what to do or think.. is it a miscarriage or something else?
