Nervous Wreck

Keke • Happily married to the sexist man I know. We had been trying to conceive after our first miscarriage for 2 yrs. Blessed to see everyday and yesterday to learn I was prego. Please pray we go full term.
So Monday I'll be 12 wks 1 day and I will be having my 1st US and hear the hest beat. Due to my weight I feel I haven't been able to find the HB with my doppler and also due to my lack of symptoms I am so freaking nervous. Oh also I had a MC 2 and a half years ago at 7wks so that makes it worse. I am so outta wack. This is driving me up the walls.. Anyone go thru the same or have any suggestions?
