Birth Control...?

I just started Birth Control a little over a month ago. And everyone's told me they gained weight...and I know people are different.
Well I gained like 5 pounds but my stomach is soooo hard... is that normal?
Answer:
If you're taking the shot then you'll defidently be gaining weight that's impossible to get rid of because it's water weight. If you take the shot then you gain weight but you are able to burn it off but only if you exercise daily. I've been taking the shot for the past 2 years and I exercise every day for an hour but the weight won't come off so I'm switching to the pill as soon as my shot expires.
