Hi. My name is Nerissa Wekesa,36 years . I gave birth in June 6th 2005. An I.U.D was inserted in October the same year. I had my period in 2nd July to 7th July...which quite regular for me according to my calendar but then again my periods started on the 24th July till now. My doctor prescribed norethisterone 5mg 3*a day for 10 days and sylate 500mg which I take 2* a day for 5 days. I'm on the second day of drug intake but still have a high flow especially in the morning. Doctor also mentioned that he'll remove the coil on 6th August next week. I have also had a history of hormonal imbalance which I don't understand. What has caused this irregular period which I've never had? Why can't I go back to using the coil after its removal? Why am I on this medication? Why is my flow heavier during the day?
