I have acrylic nails and was masturbating I think a small piece of the fake nail chipped off into my vagina but when searching there was nothing help?

I wouldn't freak out. This is likely to be shed in time and as a simple foreign body it should do no harm. You might try a simple douche to float it out but you may never be able to identify it when it goes. If you develop a discharge after a few days I would try the douche again. .
