weird CM?

I've been noticing lately that when I stick my finger up my vagina, there will be very white CM under my fingernail (I have long nails) and it smells like glue kind of? I haven't noticed any CM on my panties or when I wipe just when I put a finger up there. Is this normal? I don't have any burning or itching or any weird symptoms, just the white CM. it's like an endless amount. if it helps, I just finished a normal period and finished my fertile week. next period in 10 days, have had this CM for the past two days (that I've noticed)
