I need opinions please.

Amy
So I have pcos which causes me to bleed 24/7. Abnormal uterine bleeding. Well, it started again November 1st, and stopped dec 15
I had sex on nov 28. That was it. 
The only thing I feel is extremely tired. No cramping. Nothing. 
I took a hpt on Saturday but it was negative. 
So what do you ladies think? Should I retake the test? I don't know if I'm being paranoid or what. It's been a while since I had intercourse so I would think that I'm not. But the last time my bleeding stopped, I was pregnant. 
With all my pregnancies though my boobs grow a size and they haven't this time. 
The only other symptom I have is my boobs are slightly sore. But not overwhelming. 
Please tell me what you would do. Thank you
