Thanks girls, melinda, thankyou too for sharing your experiences. Believe me, i know your not trying to put doubt in my mind. Im fascinated by both the really really good things about pregnancy, and the not so good things.......this is #2 for me and i dont know why, with the first i wasnt all that concerned (what i didnt really know about didnt concern me i guess), but with this one, i feel so cautious.....
