Yes this was my 1st pregnancy.I am also only 18.I didn't think it would happen since I am 18 & my fiancee is 21.However I guess it can happen at any age.I am emotionally so confused.I was ready for a baby,but not to deal with something like this.I found a site which listed TONS of reasons a miscarriage can happen.Nobody really knows why they do though.I wish they could tell you.I am so scared of it happening again. *Sigh*
