Is it really a miscarriage ?

It’s the day before I have to go back to the doctor and my bleeding is starting to stop . Is that possible ? I thought if I was truly having a miscarriage my bleeding would be lasting longer. I’m nervous about tomorrow’s visit . I really hope god sends me a miracle and she tells me that my little bean is still in fact in there pulling through .

Short back story :

I was definitely pregnant . Went to the doctor Sunday morning because I was bleeding . I was told I was having an early on miscarriage . . She didn’t take any blood or run any tests. I went to my ob yesterday . She did an ultrasound and she said everything was fine. It looked like I passed everything .. then she went to my left side and made a 🤨 face & im looking at her like “what” then she asked if I passed anything white . I told her no.. I’ve only been bleeding . She told me she was going to take blood for a pregnancy test.. she then told me she wanted me to come tomorrow MORNING again. That’s two days in between and she wants me to come in the Morning . So do you think it’s really a miscarriage ? My bleeding is also coming to a holt and it’s only been 3 days ..

In my mind I think she seen something and she wants to confirm or deny what she seen in the ultrasound . I WAS NOT FAR ALONG. I was about 4 weeks and a couple of days . Therefore she can’t really make out anything on an ultrasound so that could be the reason she’s trying to confirm what she saw. I’ve heard of people being pregnant and they ended up miscarrying one child early along and the doctors thought they lost the baby when in reality they only lost one . Also some women bleed through the beginning and was told it was a miscarriage but they were just normally bleeding .

Could I really be having a miscarriage ?
