Weird things are happening

So, long story short...

I have PCOS and do not have periods. My man and I have sex on the weekends because of classes. I know that my chances of pregnancy are low to nothing because of it. I have been extremely tired for a week and a half now, sore boobs and nipples, food aversions and weird headaches. I took a test yesterday and it was negative. Anyone experience this before? Have any insight?
