I'm taking .5 cc of Superfact once a day, I am not sure if I should store them in the fridge and I have finished my period 3 days ago but I am still seeing spots of blood and I am having head ach.

I looked it up and it looks like headaches could be one of the side effects.
Ask the pharmacy for a pamphlet of side effects
Tell your doctor that you are having problems with it.

What I looked up said to make sure you take it WITH meals to reduce the chances of side effects.
