Since hitting my 40,s my period as changed... like many on here really heavy bleeding... having to change every two hours... migraines before period begins. This medication as slowed down my bleeding which is fine... but feel very drained and get stomach cramps more so then I did before... and the odd headache... while on the medication. Today is the first time iv had a day of work because of my periods.. feel so crap... anyone feeling like this ???
