needing a friend

I've had three miscarriages before this (with another man). Things tend to go downhill for me on the 8-9th weeks. Hitting the 8 week mark today scared me. I went to my appt last week and I was 6weeks 6 days with a steady heart rate of 136. I'm trying not to worry, but I am a mess. I've had morning sickness with this one and felt worse than I did with the others- I don't know if that's a positive or not. Today my morning sickness wasn't so bad so then I worry. Just call me a worrier :(
