help :( not sure what's wrong

hellraisedfire

I went on a cruise last week. I didn't eat excessively, but I didn't follow any healthy regime. I was a lot more active than normal though. I started my regular eating on the cruise again so I could try to be back on pace. now I'm trying to do my thing, and I feel AWFUL. it's been two weeks since TOM, but I am on BC and I'm not pregnant... I know that lol. but I have awful cramps and I feel HORRIDLY bloated. all I drank on the cruise was water and maybe a fancy drink during the night, but I don't get drunk. I feel like I'm going to pop out of my skin. what is going on?!!
