Delayed period and cramps

[Awhite518]

I was 6 days late for my period and I thought I was pregnant. I had weird cramps I've never felt before on the day I was supposed to start. I had sore boobs and sore back and had to pee a lot. I felt a weird pressure in my bladder making me feel like I always had to pee. Also, my cycle keeps changing and my period starts every month 2 days later then the last. Could I have cysts or problems ovulating? I feel ovulating pains every month but I've never been so late on my period. I also took 2 pregnancy tests and they were negative. Thanks!

Maybe try a first response pregnancy test, they are most sensitive. A number of things could have caused delay. For example stress
