I have understood your problem.
In fact Sprintec
is a birth control pill which contains Ethinyl estradiol and norgestimate
. Apart from birth control they are supposed to regularise the menses.
If you are having so much problem with Sprintec for continuous 3 cycles, it is better you switch over to some other birth control pills. If even otherwise your menses are heavier, you may opt for progesterone
dominant pills. Please report to your Gynaecologist your problem. He/she will change your pills to suitable combination and brand.
Also, since you are bleeding so much, better start some iron preparation and proteins
to recoup the lost blood.
I hope I have guided you on right path.
