Could I be pregnant? (TMI Details)

My SO and I had unprotected sex almost 4 weeks ago and then again 2 weeks ago on the first day of my fertility week. I am experiencing way more acne, headaches, going pee way more, more thirsty, my breast are little bit more swollen, my pelvic area has slight cramps, I have clear and white discharge, I'm feeling very bloated, am neasous, and go from hungry and not hungry in minutes, I am also craving spicy things like no bodies business. I had a weird "period" like thing about 3 weeks ago and it was nothing like my normal periods. Light, no clots, watery, no cramps, pink and brown instead of dark red.
