Ok, so this is the second time this week that I've had really bad stomach pains this week. I also feel like I just need to throw up. I had a pregnancy scare a few weeks back (but proceeded to get my period on time!). These pains happen after I eat! Last time I had Taco Bell (I know I know). This time it was a home made burger, with eggs, salsa, and greens. Could my stomach just be starting to get super sensitive to grease or could this be constipation? When this happened the first time (last time) the stomach pain was still there in the morning.
