Hi,
Thanks for posting in HCM.
I understand your concern.
Birth control is a way to prevent pregnancy. Using pills as birth control is hormonal mode of
contraception. The hormones used include estrogen and
progesterone. When birth control pills are taken correctly, it is up to 99.9% effective.
Seasonique is a type of extended-cycle pills, which use a different configuration of hormones.
Common Side effects include: Nausea, Weight gain, Sore or swollen breasts,
Abdominal pain,
Spotting between periods, Lighter periods and Mood changes.
In case you need to change the mode of contraception, you need to consult Gynecologist so that you would be advised the one which would suit you.
In case you keep switching over from one pill to another, it may not ensure protection completely and you might experience many side effects associated with them.
Hope the information provided would be useful.
All the best.
