I started my period 2 weeks late and now when I eat I throw everything up?
Can I be pregnant? Or is it cause I gave up meat for lent and I haven't eaten any in 40 days.
Is my body just not used to eating meat? Someone help?

Is your period lighter than usual, or any different?

If you are sexually active there is always a chance you could be pregnant. You should consider taking a pregnancy test. You can also just be feeling sick. When you have an extreme change in diet/exercise/sleep/stress habits, this can cause you to be late or miss a period. But the only way to be sure is to pee on that little stick :)
