I am 37 years old and weighs 170 lbs which is 10 lbs more the weight i had before having my fourth child in January 2013. Prior to my last pregnancy my monthly period was clock work. After my baby in 2013 i decided to use the copper T which i used for exactly 15 months before removing it- i could not bear the heavy periods that would extend over seven days compared to my usual 5 days. Upon removal of the IUD i was told by my doctor that i had a cervical infection and was given treatment for two weeks. Upon review i was told by my doc that everything was ok now. After removing the IUD my period came and endured for my usual 5 days before inserting the IUD, however after that, and to date whenever i am having my period the blood is barely red and is more very light pink or close to brown. What could be hapenning to me?
