Miscarriage driving me crazy!

I went to the dr today to do my first ultrasound. According to my last period I am 8 weeks today. I went in with my son and husband. The ultrasonographer did a vaginal ultrasound and was having a hard time finding the baby's heart beat. That immediately made me worry and think the worst. She was quiet and kept trying different angle and things to find a heart beat but no luck other than a really "faint" one. She mentioned that baby is also measuring 6 weeks and not 8. At this point my heart dropped. At the time when she said that I automatically assumed a miscarriage and thought of the worst. At the end of the ultrasound she said she would relay this to my dr and recommend to see me in one week to see if there was any progress.

My dr then reiterate that the baby is measuring at 6 weeks and not 8. She said it could be a sign of a miscarriage or than it can be that I ovulated later than what we think. From one extreme to the other I'm left thinking the worst. They drew blood today and would like to recheck it in 2 days to compare. At that time it will give us more answers in which direction this pregnancy is going.

I'm in disbelief. I'm in shock. I'm preparing for the worst and I'm praying for the best. My mind is going in every direction. I'm trying to read every post possible in this app just to get some peace in mind until I know for sure. Although I know every women is different and every pregnancy is different there's just want some reassurance that everything will be ok

This pregnancy was unplanned but the moment we found out I was pregnant we have been super excited. I always feared this for my 1st pregnancy but never thought this would happen with my second

If any one of u ladies could post any similar stories I would really appreciate it... these are gonna be the longest most hardest days for me. ❤
