Please Help

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.
Ok I have had a Mc at 7wks. I am now in my 2nd pregnancy at 11 wks I haven't heard the heartbeat and am so neverous. I feel like I'm going crazy.. For those plus size mommies and mommies to be have you ever used a doppler and how? Also at what week did your stomach start hardening and was it at the top or botttom?
