I been having back pain for the last few days. It got worst yesterday when my menses came for the 1st day. I never have this problem before. Usually if there is pain, it will be only for a while. But this time around seems to be a few days. I even came late to work. Nearly 10am. Went to see the company's doctor nearby. She gave me some pain killer. In order to see what went wrong, she advise me to have a ultrasound pelvis. Anxious to know too so i will be going soon once getting approval from my HR Manager. Been sleeping late too lately. The pain makes me difficulty to have some gd sleep.
