No period but test is negative ??

nicole

I ovulated on October 6thish (I had ovulation bleeding), I then had another spot of pink just in my cm a on the 12th. I then had cramps like I was going to start my period on the 14th but only on my lower left side but no period. My period was supposed to come on the 17th but it still hasn’t. I took a clear blue test yesterday and it was a bfn... I’ve been feeling slightly nauseous when I wake up, extremely fatigued, way more hungry than normal, and super emotional. All of this could be pms but where the heck is my period then?!
