I am so sorry for your loss! You are right everyone is different. I hope you are feeling better.
Unfortunately I did have a miscarriage. I though I was. It was my first pregnancy so I was a little freaked out about it. Never thought a miscarriage would cause so much pain and everything else that I had. I was unable to walk and even stand for almost 3 days due to so much pain. Finally today my pain has eased off. I can finally walk and everything. I couldn't eat or drink for 2 days. It was horrible. I guess every one is a little different though.
I agree with Heather. I had bleeding with all three of pregnancies, two resulted into my boys and one ended in a miscarriage. Some women just have off and on bleeds during their pregnancies, for some this results into a normal pregnancies and others not.
I wish I could give you a definite answer but sadly only your OB can. I hope tomorrow brings you a happy ending!
Unfortunatley, the only thing you can do is wait to confirm with the doctor. All of the symtoms do sound like a miscarriage, however there are some women that bleed during the first trimester of pregnancy and everything turns out just fine. Good luck!
