Pregnancy symptoms good or bad ?

Hi I'm 5 weeks pregnant and I've got really sore boobs, bloating, and cramps but I think they're all normal right the only thing I'm concerned about and need advise on is that I'm feeling quite dizzy and earlier today I had a stabbing cramp pain on the left side of my stomach when usually I'm getting cramps all over also the bottom half of my legs feel like they're burning when I walk the main thing I want to know about is that pain in my left side is that normal ? Thank you xx
