Miscarrying at home

Joanne • Angel, twin angels, with a forth, fifth and sixth angel. Rainbow boy came 7/2/20- #2 is on the way due 11/22/21

When I called my Dr's office this morning, the answering service said they don't take calls from anyone under 22 weeks, and that I would have to go to the ER if I wanted medical attention. So I am going through it at home. I have had several before but never at home, without pain meds. So my question is, have you been through this, and are there any signs I should look out for? Are contraction like pains a few mins apart normal? Any insight would be appreciated.
