HELP!!!

I have a huge problem. So about about 2 weeks ago my boyfriend and I were just chilling fully clothed and he came and I felt something on my leg( I was wearing shorts) anyway I washed it off ASAP and all was good. Later that day I started my period, now I’m into my ovulation time period and my discharge was white and milky looking and a few days earlier I was really itchy down there (I shave a day or so before so the itchiness could have came from that) I’m really freaking out. And just have a few questions.

1. Could this be a yeast infection?

2. Is this a yeast infection from pregnancy?

3. Could I have gotten pregnant from that experience?

4. Is this just normal?
