statics show that every 1 in 3 pregnancies end in miscarriage! it seems like a lot, but it really isn't because many women who have a miscarriage, don't even know they are pregnant! any woman can have a miscarriage unfortunately, even if you are healthy, it is possible.i had all day nausea for the first 3 months, but didn't get morning sickness until 9-10 weeks pregnant! after they first trimester, the chance of a miscarriage goes down to 3%. so that means that 3% pregnancies after 13 weeks end in a miscarrige, which is really sad too. but your chances greatly decrease!don't get yourself all workup about having a miscarriage, it is not good for you to stress out (although it is our motherly insinct to worry). i had a miscarriage 2 years ago, it was hard, but now i am 15 weeks pregnant!!if you ever have any problem with your pregnancy such as uncontrolable cramping (although it is very common), bleeding or leaking amonitc fluid, go see the doctor immetidly!otherwise just relax and ENJOY being pregnant!
