Since I started my period when I was twelve to now, even after having a baby (who is now 3), my periods kind of just do what they want to. I only get it about once every 3-4 months..every time I ask my GYNO she tells me to get on birth control to regulate it, but I'm trying to have another baby so that would defeat the purpose. Anyway, does anybody else experience this or is my body just strange???
