Hello!

I've been having issues of periods that last longer than 7 days and I've gone 6 months without having a period. I thought I was pregnant and I've done multiple tests which prove I'm not. Recently, I started my periods July 14 till Aug 7th then today Aug 9th I started right back up. I only went one day without having periods. I went to my obgyn and we are doing an ultrasound Tuesday. Have yall had these type of issues and what was wrong and how did you deal with it?
