Well, they could be genital warts. If they don't go away soon and you are not sure what they are, get it checked by a Doctor.

they can be several things. Could be a rash from shaving, perhaps a cyst, or even a pimple. I would suggest immediately checking with your OBGYN, though.
It is most likely a rash from shaving, it's nothing to worry about they will go away when the hair grows back a little,
