WHAT COULD THIS BE???

Monica

so about 2 years ago my cycles became very irregular (lengthy) I went to the doctor & was told i could possibly have PCOS (also noting i found out I had fibroids 5 years ago while pregnant). she put me on provera which help regulate everything for a year & i didn't want to continue them after the year so i stopped .. fast forward to now my cycle has been on for a MONTH! I've never really experienced cramping but I've been having the worst back pain since this has all started.. yesterday while on the toilet i wiped & noticed something very strange.. & i really don't know what it could be anyone else ever experienced this .. doctors appointment next week for ultrasound but my brain is shot trying to figure it out until then..
