Cycle day 44 and no period

So I'm totally new here, but this is just driving me crazy. My periods have been fairly regular since January with my cycles averaging 34 days. My last period ended on June 18th and I had unprotected sex on the 30th. My period is now a week late and I tested this morning and got a negative result. My breasts are super swollen and sore. I've been getting cramps but all I have is kinda creamy, stretchy CM. I have been getting mood swings and eating a ton. I haven't had any significant stress this past month to affect my cycle. I just can't tell if this cycle is a little wack or not. Any advice??
