TMI:: progesterone pill help please

Steff
Hello lady's, so I started my vaginal progesterone pills.  Yesterday I had thick white discharge which I assumed was normal. Last night I was woken from my sleep I felt like I started my period. My liner was completely soaked. Is this normal for these pills? Of course I'm sitting over here hoping it's pregnancy related so was just hoping for some similar stories or any input..  thank you. Sorry for the TMI questions
