I've been so dizzy here the past few days, it's bad I can barely move and the whole room will spin and I've had sore breast even longer, headaches, I'm even eating food that I've hated, I feel sick to my stomach but I'm not throwing up, I have horrible mood swings lately, yes these can all be signs of starting your period but I've had my period for a while and I never have any of these signs of it, would you say it's a possibility of being pregant bc there is a chance I could be. Opinions?
