I’ve been having some stronger cramps however no bleeding, no spotting etc. If I go to the ER :

1. Will they be able to do an ultrasound?

2. Will they do bloodwork?

3. How long will it take for the HCG tests to come back?

4. What if it is ectopic?

The cramps just feel like stronger period cramps and they go from one side to the middle and a couple days ago they were on the opposite side so I don’t believe it is ectopic. I’m just a stressed out, worried mamma.
