They will do blood work often to make sure the levels are either staying the same, or dropping.
I have them as well. Not sure what the numbers are but they've stayed the same from 6wks and on and I'm almost 20wks. I've had 2 bleeds so far and baby boy is perfect in there.
Its hard not to stress but as long as Dr does his job of monitoring your levels on at least a monthly basis (that's what I do) then you and baby should be fine :)
Yes it is very hard not to worry but thank you put some worries at ease.
I was like that with my last baby and this one thwy just checked my levels every other visit to make sure thwy wasn't rising Sid they twll u which one it was? In my case I was positive for the M antibodies which is a good if u r positive bc its to big to cross the placenta try not to stress or worry to much
