pimple on labia minora?

Hello ladies, I have a very intimate question!

I have what seems to be a pimple(?) or some sort of hard bump on my labia minora.

I don't shave near there, only trim with scissors occasionally (so no possibility of ingrown hairs!) and I shower with a gentle soap every other day. I haven't had sexual contact with anyone but my husband, and he is trustworthy, so...

My question is: has anyone else had a pimple(?) on their labia minora (inner lips of the vagina)? Is this normal? I don't know 100% if it is a pimple but a little pus came out when I squeezed it (wasn't trying to pop a pimple! just find what was hurting me and look in a mirror at it!)

Thanks ladies
