I have a light a period, usually it's not very heavy but defiantly heavier that whats happening now, I was late 2 days and the pains about the same, ( I get bad cramps). Lately a lot of stress has been put on me and Ive had problems because of it with memory and concentrating and sleep, and I was wondering if that has something to do with it. I do have sex but rarely, and I kinda freaking out right now. Please help. I am overweight, I'm currently 78kgs.
