Weird mashed potato discharge?

Every now and then I get a weird discharge, NOT cottage cheesy but more mashed potato-y (I've had a YI before and the discharge looked totally different than now). I know this is gross but if I put it in a bowl next to mashed potatoes you wouldn't know the difference. I haven't had any other symptoms, I've had an IUD since Jan 13 and have had on-and-off spotting, but no itchiness or soreness or irritation. Just the weird discharge. Anyone have similar?? Why are vaginas so obnoxious sometimes?? 😫
