Small white bumps in vagina opening, what is it?

Ive had sexual intercourse not too long ago. however my vagina started to become itchy and I checked it. I had these small white bumps and it bothered me. It itches but I worn cotton panties and washed it with cold water to ease the itch. Although it doesn't have a foul smell. Is this a yeast infection? Please help.

Looks like yeast infection

Does a yeast infection include vagina being swollen?

you have a yeast infection, does it smell sorta sweet ? A yeast infection can cause your vagina to be swollen, itchy and have an off odor.
