Baby Doppler Help!

I have been using a fetal Doppler since 9 weeks. A little back story on my pregnancy. I found out that it was identical twins, and possibly a triplet hiding behind baby A. Went into next appointment and they said the twin passed away and that it was only one. Well I have been hearing two different speed heart rates and maybe my heart is just longing for a second baby, but maybe it's possible they saw a passed triplet and there are still two in there? I haven't had a scan since 9 weeks and I am currently 15 with next US at 18 weeks. If anyone is willing and familiar with a Doppler will they please message me on this app and let me text them the videos I took. I know it probably sounds desperate and pathetic but I swear one is NOTICEABLY way faster than the other. My bump is also HUGE for 15 weeks. FTM here.
