I don’t know

I think my mind is playing tricks on me. I’m late but I have PCOS so that’s not abnormal. Just found out not to long ago about that. I have been cramping for two weeks, haven’t been wanting to eat, can’t eat then take a nap or I will wake up nauseous, and I have been having headaches for no reason at all. I have taken four test and they all keep coming back negative. I should be 5wks and 1 day today if I was. But I don’t know and I’m starting to think I should call my dr.
