TMI but IM AT A LOSS AS TO WHAT THIS IS

So I took a shower today and I wear panty liners since I have some discharge and it makes me feel cleaner to change them. Anyways, I just took my underwear off with my yoga pants and after my shower I went to throw the liner away and my clothes in the basket when I noticed this on the liner! I have NO IDEA what it is, best way I can describe it is like tiny squishy orbs? Seriously the weirdest thing I've EVER seen. Has anyone else experienced this and have any sort of insight? I'm 29w4d. 
HELP SOS.
