Just a bug?

This is going to be a TMI but the week before my period I'd been pooping a lot. I've been under a lot of stress, there's been a  move and change in diet - I went from home cooked meals to crappy college living. I got my period as usual (my second period since I had any real reason to fear a pregnancy scare.) and I mentioned to my mom how bad my period gets and that I get really sick and I should probably seek help. She said she hoped I wasn't pregnant and said I can get pregnant and still have my period...I posted here about my period woes before this comment and everyone said it was normal but I could do something about it. I got my period Tuesday, Friday I came down with a cold which I still have. I'm still using the bathroom a far amount but I'm chalking it up to being the cold I have. My next period is in 17 days. Should I worry? What's going on? My mom's comment really bugged me.
