About 25 percent of known pregnancies end in miscarriage. However, the rate is believed to be higher because many miscarriages occur very early in pregnancy, before a woman may know that she is pregnant.

Miscarriages are usually in the first twelve weeks of the pregnancy. Once you get thru the first trimester it takes a bit to have a miscarriage - a serious fall down stairs, illness, extreme stress, etc. It usually doesn't "just happen" after you've passed the third month of pregnancy.

I worry about this too. I want to know if there's anything I can do to help prevent it. All people keep telling me is to stop worrying, but i'm not good at that!

Awww theres nothing u can do to prevent a miscarriage just do everything u can to make sure u have a helthy pregnancy taking ur vitamins, good diet etc...
Good luck anyway hope everything goes ok with you...

Fingers crossed for you let us know how u go on x x x

Is there any history of it in your family? I haven't really done any research, so I don't know if this makes sense, but all of my aunts had miscarriages, so did their daughters, my mother did right before she had me, then I just had one about 3 months ago... I guess it makes it more common? Who knows maybe they're not even linked...
