This is my first cycle using Glow ttc. And I'm not sure if these feelings are in my head and my body is just having these symptoms to make me think I'm pregnant.

My husband and me had sex a few days before my fertile days and then two days back to back during the fertile days. On Saturday night we were eating pizza and 2 slices in I lost my appetite completely and just a few minutes later felt nauseous. Pretty much the same thing Sunday night but we had BBQ ribs for supper. Only one rib in and lost my appetite and felt nauseous a few minutes later. Then today, Monday, going to work I had brought me some poptarts (like always). Not even half way through the first I lost my appetite again. But a few hours later felt even more nauseous and a little light headed.

Should I take a pregnancy test now or should I wait?
