I think I am pregnant and devastated.?

I do think you're pregnant. Stop taking the meds just in case you are pregnant. Then see a doctor and see what he/she suggests because your symptoms sound like a "textbook pregnancy". As for your husband, if he doesn't know of your possible pregnancy, TELL HIM. This could maybe change his mind about meds. If he still refuses, then you have hope. Your baby Wont come Into a broken family if the marriage is ended before his birth. Single mom is a hard job but not impossible. And you still may find a boyfriend.
