Nervous wreck!

Well I've been kind of a nervous wreck lately. I cant stop thinking about what if something happenes to this baby. Alot of women on this site have had 2nd or 3rd trimester losses. I just cant imagine. Then about a week ago I found out my old friend, from when I was growing up, had a baby and a week later it passed away. Im so scared something is going to happen to this baby. What if at my 20 weeks scan they find something wrong! The internet doesnt help because all day I research what could cause this or that. Its make me scary. To make matter worse I just went to the bathroom and my heart dropped. I saw blood, it was coming from the outside but I didnt know that till I got in the mirror and started examining it. Im still sick to my stomache because of it. I went again of course and its fine now and I can actually see where I'm riped or irritated. Earlier I didnt even know I was irritated so the sight of blood about made me have a heartattack.Well thats all for now. Hugs Monica.
