Can Yeast Infection Cause Vaginal Lumps With Itching And Pain?

I' 17 years old 5'1" and I weight 105. I am also pregnant. A few months back I had gotten chlamydia I was treated but I didn't sustain from sex the full week and was then treated for it again. I went back for the check up and it was all cleared up. Just a few days ago I was having sex with my partner (he is the only person I have been with in 5 months) we had sex a few times that day and the final time my vagina had hurt so bad I told him enough. The next day it was still very painful it had hurt to even sit on hard surfaces, touch and itched quite a bit. Later that night I thought I had came down with the flu, very cold and week. The next day I was going to go see my obgyn and I had discovered a few tiny white bumps in my vagina close to the vaginal canal. I went to my obgyn and told him all of this he took a look and I had a yeast infection. He also said that I might have herpes but it doesn't look exactly like it so he had to take a swab and send it into a lab for results. What do you think it is? I'm worried because this is the first time anything like this has happened. I've never had bumps like this ever.
