recently I started birth control and I am almost done with the first pack So I should already have or am getting my period soon right.? But I looked on the paper they gave me with birth control and it said some side effects is that it may make my period so light that it will just be a brown stain? And I’ve had nothing bad brownish stuff and discharge. How do I know if this is actually my period or not? Because I’m so confused on how I track something that isn’t an actual period ?
