Discharge

I’m currently on cycle day 18 and last night I had weird discharge , white lotion like, was quite a lot , has anyone else experienced this or know what it means?? , I’ve had 3 kids and currently trying for another baby we are currently 3 months into trying, I’m trying to not get my hopes up as I can’t remember seeing this kind of discharge before. I’ve tried to use doctor google to find answers but as predicted, useless says pre ovulation or post ovulation or early pregnancy and I guess I just want to know if anyone else has experienced this and it been a sign of pregnancy, I’ve never had any issues having babies (this is the first planned baby) and we are struggling to conceive, going crazy.
