Does everyone who starts the minipill experience spotting ? can spotting make you anemic and how long does the spotting last ? im taking it to regulate prolonged periods so spotting worries me. thank you?

Irregular bleeding or spotting is common in the first three to four months after you start taking the minipill. This should subside once your body adjusts to the medication. You may experience spotting later on if you've missed or skipped a dose or your body experiences stress: change in weight, new exercise program, loss of sleep, certain medications.

You could check your blood count in 1 month to be sure.
