Symptoms

So my period ended about a week ago and my chart states I’m in my ovulation week, however I’m having horrible nausea the same type of nausea I experienced with my first, food cravings, headache, slight cramps etc..all these symptoms are a tad unusual for me during my ovulation week so I’m just wondering if maybe I should take a test just in case...I highly doubt I’m pregnant since I just had my period and we’ve only had sex once since my period ended before my ovulation week. I’m just trying to figure out what this nausea fatigue bloat headache shit is all about. TIA
