Please help me

So I've always had regular 28 day cycles until November when i had a 31 day cycle and in December I had 35 dat cycle. Currently I'm at 32 in my cycle. My bf and I had sex but he wore and condom and he also pulled out before he came in the condom about 2 and a half weeks ago. Here is what I've been experiencing. I've been super stressed.

- pale yellow discharge(a lot)

- mood swings

- breakouts

- no change in boobs or soreness

- no cramps (I usually don't get any)!

- no implantation bleeding

- not feeling sick

**could I be pregnant?
