So today I had cramps for maybe a few seconds or so. Then later on in the morning I began to feel nauseous but I didn't have the urge to puke just yet. Later on in the afternoon I was in the store walking around and I kept getting weird stomach cramps. Like I had just got done running or something. I'm also extremely tired today and want to take a nap (I NEVER TAKE NAPS). Could this be possible pregnancy symptoms?
