Pap smear while pregnant?!?

Angela • Mom to 3

So i'm supposed to get a papsmear done next week because I've never had one (im only 20). I'm only nervous because I'm worried it will somehow effect the baby. My midwife says its a really good idea to have it done and i mostly agree. Does anyone have any experiences they could share to help me make up my mind? I want to hear both good and bad experiences please. Has anyone ever miscarried due to a pap smear?

Thank you all so much.
