Help!!

I've been experiencing major bloating the last 2 days & ate around 4 pieces of pizza, a salad, & half a bag of chips & have had some crazy headaches the last 2 days! This morning it started as a headache switched to a migraine now I'm back at a headache, does anyone have any solutions for these headaches I don't know what to do & I don't want to take anything because we're TTC. I'm not supposed to start my period for another week so idk if it's just pms because I don't get any warning other than im extra moody the day before I start. Any advice would be helpful!!
