Hi Sarah,
How excitng you are so close. Perhaps ring your pharmacist about it? I know when I was in early labour and at home the nurses said to take one of the panadeines, can't remember which that you could get over the counter. and I have areally lovely pharmacist who told me that it could depress respiratory function in the baby. Anyway, I took it, and DD did have some respiratory probs. post birth that they could never actually pinpoint why and they resolved after about 48 hours. so drugs do have effects on bubs and not necessarily the same effects tehy have on us.
