Still waiting on second cycle pp

E
So I got my first period about 6 weeks pp. However, I'm still waiting on my second period. I am now 13 weeks pp. I have even tested to see if possibly I'm pregnant and the tests are negative. I'm sure my cycles are out of whack but has anyone else experienced this?
