am i in denial

so I had my period just under 2 weeks ago, lasted about 4 days and had horrendous cramps on day 2. anyway the last couple of days been feeling so nauseous, actually had to come home from work today because I thought I was going to be sick, but feel a bit better now?! I don't know if it's all psychological or if there is a small possibility I'm pregnant. I'm a poas addict so don't know if I'm just looking for another excuse to take one 😂🙈
