Drop in hcg

Amanda • Ttc#2 for a long time now got glow app in feb mid cycle I really want a fall baby so I`m making every effort next month
My hcg went from 48000 to 46000 no cramping no more spotting. Had a slight bit last week but it was brown and vary minimal. Had more blood drawn today follow up us on thur hoping for a lil flicker of a heartbeat and that this lil fighter will defy the docs prediction of a miscarriage.
​Has anyone else had a drop in hcg but still have a viable pregnancy???
