I did have the iv drip. I had no choice in the matter, or at least I thought I didn't. Anyway, I am glad I did, because I did run a fever while I was delivering, they also had to give ds antibiotics at birth, because of the fever. But everything turned out well.
Like Erin Pavlina said, the risks really are very small, and it is up to you, but if you decide to or have to have the iv, I just want to let you know it wasn't that bad. Actually the iv was mobile, but I wasn't. I had an epidural, because I also had the dreaded pit drop in that iv-now that is bad!!!, but up until then, when it was just the antibiotic, everything was fine.
