Hi, this is my third pregnancy and I know I should be ok with everything, but i'm not. I'm not sure if it's just me or what. With this pregnancy I found out way early I was pregnant. I'm 16 weeks and haven't gained any weight. When I went to the doctor at 13 weeks, the dr. couldn't almost find the heartbeat and when she did it was very faint, but she said it was a good heartbeat. Ever since I found out I was pregnant i've always had a bad feeling something is going to be wrong. I was never like this with my other 2 pregnancies. I don't know what's going on, but it's got me constantly stressed out which probably isn't good.
