What are the chances?

So here is my calendar and we BDd I'd say a lot... it's been over ten days post ovulation but my test came back negative. At some point I did feel cramps and I was very hopeful. My period should be starting in couple of days... I have had a very little strick of blood in discharge today (sorry TMI) and my breasts are hurting and I am cramping and feeling bloated. What are the chances that it's not PMS? I am crossing my fingers for my period not to come
