Confused

In December I had a very normal period that lasted 3 day max. Ended the 27th
On the 3rd unprotected sex (during my fertile window)
Got my next period the 18th. Which was a week early for me. It was very heavy for a good 6 hours and then was brown spotting for the next 4 days. That's just not like my period. 
Now for the first time ever I have cramping during ovulation (assuming I'm not pregnant) and extreme amounts of discharge. Which I have never experienced during ovulation. 
Anyone ever experience some of these symptoms. I am so impatient to wait around for a test. And my breasts are not swollen. I've been toning and losing weight pretty steadily so if anything I have lost weight. Any tips?
