Is it normal to have a 23 day cycle




















You may still notice changes from time to time. The length of your cycle depends on your hormones, which can fluctuate due to factors like diet , stress , jet lag , working night shifts, exercise, or taking an emergency contraception pill the morning-after pill Heavy cigarette smoking, as well as chronic and excessive alcohol consumption may also affect cycle length or variation This could be due to health conditions like polycystic ovary syndrome PCOS or a thyroid disorder 22, Inconsistent ovulation and variable periods are also more likely to occur during certain phases of life, such as during adolescence, after birth, while breastfeeding, and during perimenopause the transition to menopause 1,24, Combined hormonal birth control —like the pill, the vaginal ring, or the patch—release synthetic forms of estrogen and progesterone into your body When taken as directed, the hormones in these types of birth control prevent your ovaries from preparing and releasing eggs The bleeding you experience on combined hormonal birth control is not a real period.

Bleeding on the birth control pill will happen during the placebo no-hormone days, due to the withdrawal of hormones. This will make the timing of your bleeding predictable depending on how many active hormone-containing pills are taken before a break. Sometimes the placebo or pill-free days happen after 84 active pills, resulting in bleeding about every three months Some pills have no break in active pills at all, meaning people may have no bleeding at all while taking this type of pill When you first start taking the pill or if you take your pills inconsistently, you may experience spotting or breakthrough bleeding 9, The vaginal ring and patch are often dosed across a four week cycle The vaginal ring contains both estrogen and progestin and is inserted into the vagina for 21 days and then removed for seven days, which then causes bleeding Both of these methods will cause withdrawal bleeds to occur about every 28 days Using birth control in this way will cause you to have bleeding whenever you decide to take a break from the hormones.

Bleeding will occur when you stop taking active pills, or remove the ring or patch 1. Breakthrough bleeding or spotting is common with extended and continuous use There are many different types of hormonal birth control, containing differing types and levels of hormones. Some types of birth control do not contain any estrogen and only contain progestin—a synthetic form of progesterone These methods include progestin-only pills the mini-pill , progestin injections the shot , progestin implants, or hormonal IUDs When using progestin-only birth control pills, you may not have a typical bleeding pattern.

Progestin-only pills affect reproductive hormonal cycling by often preventing the ovaries from preparing and releasing mature eggs that can be fertilized by sperm They also decrease and thin out the typical growth of the uterine lining We've all heard that women are supposed to have day cycles between periods Case in point: Some of us got our first periods at age 9 while others went into the teen years having never menstruated.

But did you know that a woman who has a day cycle might have a different level of fertility than someone who gets her period every 30 days? And that the age at which you had your first period could have an effect on your baby-making odds as well? According to a study from Boston University, both length of menstrual cycles and onset of menstruation can affect fertility.

These findings appear in Annals of Epidemiology and are based on the study of more than 2, women who were trying to conceive. The women responded to questionnaires detailing characteristics of their menstrual cycles, and after taking a good look at the data, researchers determined that women with short cycles 26 days or fewer had lower odds of getting pregnant.

Similarly, women who started menstruated before age 12 had reduced fertility when compared to women who started menstruating between 12 and 13 years old. According to the study's authors, a short menstrual cycle could signal a narrow fertile window or ovarian aging, and may also reflect a lack of ovulation we don't have to tell you how important ovulation is when you're trying to get pregnant!

While the link between early onset of menstruation and fertility isn't quite explained, it's an interesting one to consider—and Boston University's Pregnancy Study Online initiative is ongoing, so hopefully we'll have a clear picture of how this works soon.
