Progesterone side effects vs Pregnancy symptoms

I'm taking progesterone suppositories and I'm 6 weeks 4 days. I'm worried that my symptoms (mild nausea and sore nipples) are from the medication and not actual pregnancy symptoms. I have a history of miscarriages and I've heard the sicker you are, the more likely you have a healthy pregnancy. Is it weird that I actually wish I would wake up tomorrow with new terrible morning sickness?!
