Hoping for a rainbow baby!

I just suffered an MC in August. My AF was due the 23, stil no show. I've been nauseated for almost a week now starting at about 3 am and it lasts all day until around 4:00 pm. I'm scared to take a test because I don't want to go through another MC. I thought I was out this month since they say you don't usually ovulate right after. I guess I will be calling the Dr today. Prayers would be greatly appreciated!
