What could these bumps be?

Just today I noticed three flesh-coloured bumps on my vagina lips. They also seem quite hard to the touch. Thought they were ingrown hairs at first so I tried to pop them. They didn't pop and have since started hurting when I touch them. Think it's also important to note that I am sexually active but have been with the same partner for almost a year now. And I have also just had a gyno appointment about 2 weeks ago and she didn't see anything wrong. Just want to know if they're a cause of concern and if I should book another appointment with the gyno. (I'm not sure how well they can be seen in the pictures but they were the best I could do)

Where are the three bumps located–are they clustered together or do they seem to be spread out just randomly? And are they just on one or both sides of your body?

How big is each bump?

Also, can you see a little hole or anything sticking out of the bumps (like you could with an ingrown hair)?

One is located on the outside of my outer labia. The other two are also located on my outer labia but more inwards.
They are not clustered and seem to be spread out randomly.
Yes, they are on both sides of my body.
I would say the biggest is about 0.5 cm and they decrease in size from there.
And no I cannot see a hole or any hairs sticking out.
