Pcos and pregnancy

Patient: I was diagnosed with pcos and was give clomid and metrofin I did my 5 day cycle of clomid 3 weeks ago. I have been having pregnancy symptoms for the past 4 days but the hpt came out negative I have taken 3.. I was wondering if the medicine is causing me to feel pregnant or maybe I could be pregnant. some of the symptoms have been dizziness, light cramps,nausea, things taste funny like metallic and I can’t stand certain food smells.
