Possible Early Pregnancy, and Beer?

Soooo I could be pregnant, not sure. Had sex four times while ovulating, not on birth control, had one condom break, other three times didn't use a condom. Will know in the next few weeks. My breasts are suddenly sore to squeeze. I have increased vaginal discharge. And I'm just constantly tired. Tonight I had a beer (same beer I always get) and suddenly it is not sitting well with me. Instantly had acid reflex and I threw it up when I got home.
