do any mamas know if periods are supposed to get heavier with each cycle? I am 8 months post partum and am having my 3rd period and I have bled thru a super absorbancy tampon twice today.... my periods have never ever been heavy like this... I am not on birth control since I had a tubal when I had my daughter...
