I started my menstration right after my eleveth birthday and these bumps appeared a couple of days before I started my period. Now I'm 35 and these bumps still appear like clock work. I have yearly exams and I have not been diognosed with an std. I'm to embarresed to ask my doctor about these bumps. I just want to know if this is normal or do I have an std. I didn't start having sex until I was 15 so I never thought it could be one.
