No prenatal care until 24 weeks.

So just like the title said, I won't be able to receive prenatal care until 24 weeks. Husband had a job change so unfortunately we have to wait 90 days until we qualify for health insurance. Tried contacting every insurance company possible, even government and was denied because pregnancy is not a qualifying event. I want to get an elective ultrasound but everywhere I'm checking is saying I need to bring some kind of proof that I've received prenatal care. I just want to know that my baby is healthy and growing fine. Any advice? It's a shitty situation.
