3 days before my period was supposed to start I started bleeding (only when I used the bathroom) well it lasted for 2 days now I'm only spotting, I have been feeling very tired, dizzy, loss of appetite (but when I do get hungry, I have been craving chicken pizza and cheeseburgers), I have had a headache for 2 days now, all I wanna do is lay around, me an my man have been trying to have a baby, is it possible I'm pregnant?
