Pea sized lump on the tip of clitoris. REALLY WORRIED! Please help.

I noticed a small growth on my clitoris a couple of months back, I already had an appointment with the sexual health nurse so she told me to wait till the results come back from my STI screening because she thought it was a skin tag or a wart. The results came back and It was all clear. I havent been to my doctors since because I thought it was nothing but I have noticed that it has got bigger, it is about the size of a pea, it isnt painful but uncomfortable because it is rubbing on my underwear, Ive also had abnormal periods and pain for years now, I had an abnormal smear then a colposcopy but the cells went back to normal and I have had a hysteroscopy too but they couldnt find anything abnormal, this was about a year or two ago. Im just looking for piece of mind. Im worrying myself sick and I can't get to the docs till monday. Can anyone help please? Im thinking the worse.
