Advice needed 🙈

Today I am supposed to be 6 weeks 5 days pregnant, 18 months ago i had a 34 week stillbirth and prior to that I had 3 back to back early miscarriages *5th pregnancy and no living children* Last Friday at 6 weeks I went and had a private HCG beta done as my clear blue digital was showing 2-3 one day and then 1-2 another day which really worried me, that blood test came back at 192 which is extremely low for 6 weeks and I know deep down in my heart it’s not viable…my OB said to sit tight, I have an early scan booked in with him for tomorrow afternoon. I have no bleeding or cramping and I am taking cyclogest and baby aspirin as per my doctors protocol. Just trying to prepare myself ahead of tomorrow because I am so so confused…with previous miscarriages I would’ve had very faint lines on tests and spotting and pain by now & with my still born daughter I had hyperemisis and HCG was so high by now. I have added in tests from this morning and yesterday - clear blue digital showed pregnant 2-3 yesterday. Sorry for the long post! 🙈
