Please HELP ME WITH ALL YOU CAN!

So i should be 10weeks pregnant today as per my LMP but i know and blv for sure i didnt ovulate on time and it wasnt on the 14th day from my period! Because i was active after 20days past my last period! As i have PCOS i know i dont ovulate regular and my BFP came really late after i missed my period for 10days! So this ultrasound was of 2weeks ago and they said its empty and called me for D&C and i said no i wanted to wait because i see a yolk and and something inside the gestational sac because they said there was no yolk or foetal pole! My next appointment for US is today and im scared to go..i didnt bleed at all in my pregnancy just had few little cramps 2days back and im devastated i dont want to let go this is my very first pregnancy and i know im not 10weeks! Me and my hubby we both were so happy and still hoping for something positive to happen! I know this isnt a shade or anything its my baby on the right side of the corner inside the sac!
