All woman have different pregnancy symptoms so it's hard to say for sure what is going on. If you are really worried call your doc. I have never had a miscarriage but I'm pretty sure that if it was that you would have lots of cramping and you would be bleeding. But I will tell you that when I was pregnant with my first I only had sore boobs the week I missed my period (so at about week 4) and then it went away. And i didn't start getting morning sickness until week 9 or10. With my second I had a few days of feeling sick right around 4 weeks and then it went away until I was about 8 weeks along which it then came back in full force LOL.
