symptoms?

This past weekend I noticed that I was going to pee way more than usual. Like I would go then 20 mins later i would have to go again. I thought it was a uti but it didn't hurt or burn &I I was going decent amount not just a lil. So my cousin asked me if I was pregnant. Now I've noticed that every time I eat Burger King I start feeling sick to my stomach. I've had hiccups quite a bit &I I rarely get hiccups. I was cramping last Thursday night. But I haven't cramped anymore. Are these symptoms of pregnancy? Really need someone's advice &I help. Thanks in advance
