Hoping to get BFP

So I am 30 years old going on 31 and have been trying conceive off and on for years. My period for the last six months has been 29 days on average. I am currently on cycle day 32. Three days ago my breasts starting hurting and they never get sore. Then I had uterine cramps and I usually get those and then my cycle starts. I was expecting AF to arrive and its didnt. The cramps have subsided but my breasts are still sore but not as bad.I am also bloated and have been eating more frequently. I have taken pregnacy tests for last seven days and they are negative. Do you think this could be my time? Or is something else going on?
