Can hospitals run the tests I need?

A❤

Had some light spotting when wiped last night. Of course I freaked out. And intermittent cramping past couple days. It's Sunday so my doctors is closed. But can I go to the ER and get an ultrasound and blood tests? Do they do that? Iv had a past blighted ovum last year so obviously I'm more than worried. Although this morning I did not see more spotting. But I'd love peace of mind.
