Masturbating with acrylic nails ?

So recently I've gotten acrylic nails, they kinda have a rounded off almond shape, well...today is the first time I've masturbated while having the acrylic nails, everything was fine, until I pulled my fingers out and there was blood under my nails? Has this happened to anyone else ? Did I cut my vagina? Im very concerned.

(Note: I did not get my period so the blood isn't from that.)
