Um advice ??

My fertility window opens in 6 days. I wore a panty liner and the discharge dried up. It had no smell but it was a light yellow. I then stuck my finger in me and pull it out and the discharge was white with no smell. I looked it up and it said it was normal, my family and female friends said it’s normal as long as it has no smell. I’ve had this before I even started having sex. Is it really normal ? Has anyone else dealt with this before ??
