So i had my mirena out on tues then thursday i had some very very light spotting then yesterday i had light bleeding resembling the beginning of myperiod. But then it stopped last night, nothing over night or that gush feeling in the morning. Can this be a 1 day period? Should i mark it that way? I have had a period in 2 years on the mirena after having it in for 4 yearz, mind you. Please help?! I dont know if i should mark this as a period or not....?
