I was 8 weeks and 3 day

But I came in today and doc told ms I had miscarriage 😟😫 I'm so up set she said my HCG LEVELS went from 2 the to 0. Does anyone know how long you can try for other baby after miscarriage? Like I still feel like I have a baby In me my belly hard its getting bigger and its been two weeks since I had miscarriage.. They have not done ultrasound. Will they give you one if you ask ?
