There is something wrong..

Mary • 27, from Utah, I have one 2 yr old son and a baby on the way!
I worry alot during pregnancy but this time I truely feel that something is really wrong. With my first baby I used a home fetal doppler and it arrived in the mail when I was 9 weeks along, I instantly heard the heartbeat loud and steady and clear.. so I'm guessing if I got it earlier I still would have heard the heartbeat at even 8 weeks. So this time around I tried listening at 7 weeks and didn't hear anything so I just assumed it was way too early. Tried again at 8 weeks and heard nothing, I was a little worried but figured maybe it's just still to early and maybe the baby is positioned differently this time and maybe that's why. But now I'm a couple days over 9 weeks and still nothing.. all I hear is some bubbley sounds and my own heartbeat. And trust me, i checked every inch of my uterous and then some. So now I legitimately feel like something is wrong. Plus I feel I should be showing more by now, especially sense this is my second baby. I had a doc appointment last week and they didn't try to listen to the baby and they said sense I'm certain of my last period date I won't have any ultrasound until I'm 20 weeks along. Which kinda pisses me off cause I wanted to have the vaginal ultrasound just to be sure it's in there and still and alive. I don't have another appointment for 4 more weeks and I'm already thinkin maybe the baby stopped growing a while ago. I know some woman don't know how to use the doppler right, but I do know how to use it... some ppl still say I'm worrying for nothing. But wouldn't you girls be worried at this point? Or do u think I'm still just jumping to conclusion? And what would u girls do? Wouldn't u wanna get in asap for an ultrasound or would u just wait? I don't really wanna wait another month just to find out the baby has been dead inside me for that entire time. Especially sense my husband and I are trying to have another baby asap. I'd like to know for sure and do what needs to be done to try again asap. Still no blood, I still have every symptom of pregnancy. So I dunno what to think, all i know is I'm worried now. Twins run in the family and a few ppl for some reason think I'm having twins (just goin off of a feeling I guess and how sick I am) but I dunno about that. But it did make me wonder that if I was actually having twins, is it possible they would be smaller than the average baby and so it would take longer to hear the heartbeats? I know that's alot of questions and freak-outs.. sorry. Just want some opinions while waiting to get in with a doc again. Thanx..
