Confused

Cassie

So I have been getting nauseous and my boobs are sore and feel very heavy also I'm not spotting like I normally do before my period comes. So Sunday we decided to test even though my period was five days away....it was negative 👎. Now I feel like I'm not going to be pregnant at all. I don't know if I should take another test on the day my period due or not? I also have PCOS and now I'm worried that my periods are going to start getting messed up. So confused on what to do!!
