I don't want to take a pregnancy test for a few more days but I've noticed some changes with my body. First off, my period is only a couple days late. Aboit a week ago or so, I've suddenly developed allergies to something and my eyes will randomly start burning and tearing up really bad, I've tried otc meds and they're not helping. I normally poop maybe twice every three days and lately it's been 2-4 times a day. I haven't changed my diet or activity level, I'm just pooping a lot. I've felt light headed a couple times for a minute or so, but haven't felt sick at all. And lastly, my favorite perfume now smells horrible. is all of this in my head or could I be pregnant?
