I had one done when I had my first doc appointment at around 6 weeks and my doctor told me that would be the only one they'd have to do through the whole pregnancy. I really don't see how it could harm the baby I mean I wasn't that far along yet but mine went fine. I would ask your doc though him/herself why they want you to have one just so you know whats going on.

Back in my day they used to always do the pap test and always do pelvic when id go to obgyn--different now. My daughter got checked when she first went in--only had one actual visit with her dr--seen only nurses and midwives, and was delivered by someone completely else. I dont like the impersonalness of it today.
