continuing to chart bbt?

So
So yesterday i posted about getting a big shock -- a positive hpt after a mc in april. Shocking cuz i have zero symptoms. 
I know that every pregnancy is different but not having any symptoms is worrying me. Dont want to lose another!! 
Does anyone continue to chart bbt after getting a positive? Is it useful to know how pregnancy is moving along? Or is there something else that is helpful with giving me reassurance?
Thanks ladies.
