I don't think its would cause any ill affects on bubs, so long as you keep up some fluids. Especially since you said it is easing up a lil now. I was hospitalised several times with many of my pregnancy for deydration, so just dont let it get to that point. You'll know by a very dry mouth and cracked lips and feeling of extreme weakness. So long as you can drink fluid you should be pretty much right sweetie.

BUT I am not in the medical firm so if you feel you need medical advice, just give a midwife a quick call!
