I think i agree with @drqamranbashir with his diagnosis and management plan for case 2
I also agree with my other colleagues that the post probable diagnosis for case 1 is endometriosis, considering how cyclical the symptoms appear.
My differentials will include ectopic pregnancy, PID, GIT and urinary tract pathology, which are all ruled out by not being cyclical.
@omaqiin endometrosis and brucellosis are in order.
@drqamranbashir has already done justice to the brucellosis case. While the endometrosis management outlined so far is in order.
Your differentials are also on point. Good to read from you @omaqiin
