I am 25 yrs old and I am a mother of a 11month old I am on a birth control called mirena every time I ovulate I get a migrane for 3-4 days and it is so severe that I dont eat or keep anything down what I fear is that if im on this birth control will the headaches decrease or increase cause of my hormones I often ask my self how important is this birth control and how can I make myself realize that I have to deal with these headaches.. It also baffels me that I have a 3 day period and then im fine for a whole week and when I ovulate I get a severe to penetrating migrane please some one help me I am in need of encouragement and understanding :(
