ultra size wedding wear for full-figured brides

FQ: I'm 19 and I'm 12 weeks pregnant with my first child. Friday I went to a specialist and had an ultrasound and heard the heart beat and everything was normal. Then on Monday I went to my Doctor and she couldn't fine the heart beat with the Doppler she said not to be worried but I can't help but be concerned I mean not being about to find a heartbeat can be bad. Has anyone else gone through this? Do you have any advice? Thank you in advance ultra size wedding wear for full-figured brides
