Is it safe to take the pill continuously to avoid having periods?
Yes, it is — except for women who should not take the pill at all. Likewise, it is safe to continuously use some other hormonal methods, like Depo-Provera injections, the Mirena IUD, or the vaginal ring to suppress menstruation.
Many women would rather not menstruate using hormonal contraception to control their cycles for various reasons — to plan a trips, travels, athletic event, to alleviate medical conditions such as endometriosis, to avoid discomforts like PMS, for convenience, or simply because they don’t like menstruating.
