Hello!!!

I know i ovulated 27 oct , confirmed by opk and temperature rise.. i tested postive on easy@home 4 nov (8dpo?) ; on 9th nov my beta was 218 then 11th november 524.. progesterone over 40..

Well today 22nd nov we did ultrasound and only saw gestational sac and yolk sac well structured.. im worried..
