Anyone experience this?

Tee
I lost my baby is Nov and got on depo in Jan I was supposed to go for next shot in April but didn't go since coming off I have really long cycles around 49 days. I have been cramping for almost 2 weeks now and my cycle isn't due to begin until the 6th. I am feeling like my breast are heavy and mild cramps. Has anyone else experienced anything similar to this or am I alone in the world?
