Rear ended yesterday

I think we are all fine, but I was rear ended yesterday with my boyfriend and 2 year old daughter in the car. I called and spoke with a nurse right away and she assured me baby is nice a cushioned right now. I also am scheduled for my NT test Friday so that should confirm that everything is ok. I think my daughter is fine but we can’t go anywhere until the guys insurance replaces her car seat. I want us both to be seen right away, but I don’t want to risk taking her anywhere in a car seat that was in an accident. I’m so stressed out and I have a lot of neck and back pain. We only have the one car seat and I can’t pay out of pocket for one until tomorrow. I just needed to vent because I haven’t really told anyone about my pregnancy yet and I’m a little freaked out.
