I am really worried and I dont know what is wrong with me - AF arrived and it is heavy but it is brown, not red like usual start of period, I have severe cramping to the point where I am struggling to tidy the house, I feel really faint and nearly passed out when I was trying to vacuum, and I feel like I am overheating. This is not my usual period and DH is not home, I know I am being a worry wart but I have never felt like this with AF before
