I am 21yrs old and I haven't had a menstrual cycle in 2months. I have been having mild cramps on and off in different areas of my wombs. My discharge show up as thick, white, and odorless. However, a few days ago while taking a bath. I have seen a clear discharge with strains of blood. After that day, I haven't seen any bloody strains. Instead, it has went back to thick, white, and odorless discharge once again. Only thing I am having is mild cramps on and off. My breast are tender every now and then.. but not severe. Just a normal tender sensition that I tend to have when I normally have my menstrual cycles. These on and off cramps has been going on for 2months with no menstrual cycle and its worrying me. Only thing I have been craving is a whole lot of sweets and salty foods like I normally crave during the beginning of my cycle. If this is a impending menstrual cycle... please tell me what causes it?
