Should I worry ?

So I've had this bump on my vagina for what I've noticed, this week, and it's kind of at the side of my lips . But I thought that I would just shower and cleanse my self and it would go away but it got bigger, so today in the shower I wanted to see if it had gotten  smaller and when I touched it I kind of squeezed it to see what it was and puss had started coming out I assume but I'm not sure if this is something I should worry about ? Sorry if too explicit but I'm just concerned if I should call my doctor or if it's something I can fix??
