question about having a baby by a doner

my husband was cheating on me.. when I posted that topic about hearting other women.. I had a feeling, but wasn't sure if I was paranoid from my past relationships, but it turns out I know how to pick them. sure enough he was full on cheating on me.. anyways.. I'm getting my stuff together & the next time, I'll hand him the paperstuff. I know it'll happen again..

when we were happy together, I had taken clomid for us try to get pregnant, after so many rounds, I had him get tested. turns out he can't have kids..

my period has been completely messed up, I've hardly had a period for over a year (just spotting once every few months or so), I told my doctor I felt stressed and unfortunately there isn't a pill for that. she ran a bunch of tests and said I was fine. my period was fine before the clomid, I was fairly regular.

I've now been spotting for over a month.. I think it's time to go to my obgyn..

I've been thinking though, if the results happened to be bad, and I had to have a child now or wouldn't have the option in the future, do I have to put his name down as being the dad on the birth certificate since we are married?

did clomid mess your cycle up? I feel drained, and I think something is wrong with me..
