First pregnancy, should I do the membrane sweep?

So, this is my first pregnancy and I don't really know what I'm doing LOL! I am now 37 weeks, I have not had any complications during this pregnancy and I just had a check up yesterday. Well, at my check up the doctor said if I make it to 39 weeks then she would strip my membrane (only if I want her to). I want to give birth as soon as I can (pregnancy sucks and Im very anxious to meet my little one!) lol but I also heard the membrane strip can be very painful and not always help speed the process. I know I am probably jumping the gun a little because in reality I might not even have to make this decision (baby could come before 39 weeks?) but just in case, whats everyones thoughts?
