Dd was started on the OCP due to menorrhagia with iron deficiency anaemia. Despite the bleeding her periods were not painful. She is on the 7 days off on her first pack and day 2 has developed terrible period pain, it made her throw up and feel faint. I eventually got it under control after a couple of hours with mefanamic acid, buscopan and a hot bath.
Is it usual to get pains with the pill? Is it likely related to this first month only?
