TMI...Crust in panties.....

Winter • I am a 31 year old step Mother of four, consisting of two boys and two girls. I've been married for 18 months and been ttc for two months. Praying for a miracle.
I've been taking Fertibella (conceive easy) I'm noticing odorless creamy/crust in my panties at the end of the day. Is this normal? What does this mean?
