Can I get married while not having my maiden name?

I got married at 16 in michigan. It was a religious ceremony with just a certificate. There was no marriage license and in fact, I forged my moms signature on the certificate. I used this to change my last name to his. It has since been 7 years since this marriage and we havent been together since. I am now engaged and want to marry before our baby is due and I am hoping I dont have to go through the legal name change process. Can I just get married without having to change my name back to my maiden? I already changed it to my maiden with the DMV, but social security wont let me unless I have a divorce decree or legal name change, and I cant get a divorce because the marriage wasnt legal in the first place. Please help!
