Why is that a women will put on water weight in 2 months of being pregnant? with a ectopic pregnancy on top of that. like almost 30 pounds.

I am unaware: That you can separate ectopic pregnancy from regular pregnancy by following your weight. As a radiologist we usually can tell you have an ectopic pregnancy by doing an ultrasound exam. As for the weight gain this is due to the fact the baby needs all sorts of things to develop. It has an amniotic sac, and placenta - which has a certain weight and your uterus swells up as well.
