Pcos & False Negative?

Hey, just wondering if Pcos can effect the result of a home pregnancy test???

I ovulated 26th November.

And was convinced I was pregnant. I had pink spotting, nausea, sore breast, extreme fatigue, a bubbling/pulling feeling in my uterus ect.

But then I got a two day period? (Dec 11th)

It’s January 11th, my period was due jan 9th.

Usually a few days before my period I will get a brownish discharge, and period cramps which I think is old blood washing out from my last cycle. But there’s no sign of either.

I’ve been really nauseous without throwing up.

Extremely tired and getting a pulling feeling in my uterus.

Only thing is, I haven’t had sex since I ovulated in late November.

Could pcos effect the result of a test? Cause false positives? I’ve taken a couple throughout the time and all have been negative. But I’m just not convinced??

I think I’m going crazy.
