I am currently taking progesterone suppositories. Is it possible to have a miscarriage while taking it ? If it can happen, will the progesterone hide any symptoms of a miscarriage ? I also took a HPT this morning to see if my positive line has gotten darker or lighter...it looks darker than the others that I've taken. If I were going through a miscarriage, would the positive sign even show up ? I have had multiple MC's so I am a total nervous wreck. 

Taken this morning.
