Do I ovulate while taking the pill?
No ovulation: The pill inhibits the regulatory hormones FSH and LH—egg maturation and ovulation do not occur.
No false pregnancy: Instead, the pill keeps the body in the post-ovulation phase (luteal phase) continuously.
Triple protection: It suppresses ovulation, inhibits the growth of the uterine lining, and thickens cervical mucus to block sperm.
No real period: The bleeding during the pill-free interval is merely a hormonal withdrawal bleed.
Quick return to normal: About 66% of women resume ovulation as early as the first cycle after stopping the pill.
According to a representative survey by the Federal Center for Health Education (BZgA), 46% of sexually active 16- to 25-year-olds use the birth control pill. This makes it the second most commonly used form of birth control in this age group, yet many girls and women know very little about how the pill works and how it affects the menstrual cycle. We’ll explain everything: how the pill works, why you don’t ovulate while taking it, and when your ovulation will resume after you stop taking it. We’ll also introduce you to trackle as a hormone-free alternative to the pill.
What is ovulation?
To help us explain how the pill affects your cycle, we’ll first show you what happens before and after ovulation. Your cycle begins on Day 1 of your period; this phase is also called the follicular phase. During this time, follicles mature and your body prepares for a potential pregnancy. The follicular phase ends with ovulation, the most important event in your cycle.
After that, the luteal phase begins. The mature, highest-quality egg “breaks free” from the ovary and travels through the fallopian tube into the uterus. During this time, it can be fertilized. If fertilization does not occur, the egg and the built-up uterine lining are shed—menstruation begins, and a new cycle starts.
How does the birth control pill affect my cycle?
You’ve probably heard that the birth control pill tricks your body into thinking it’s pregnant. That’s a common misconception. Through a combination of hormones, the pill puts your body into a sort of permanent luteal phase—that is, the phase after ovulation has already occurred.
But how exactly does the pill affect your hormone balance?
To understand this, let’s start with a brief explanation of how the hormones in the female cycle work. You can also find a more detailed explanation in our other blog post about the female cycle. The hormones FSH and LH trigger the growth of a follicle, followed by ovulation and the formation of a corpus luteum. Estrogen and progesterone, on the other hand, influence the uterine lining and cervical mucus production. The processes that occur during the female cycle depend on fluctuations in these hormones, which also influence one another.
What changes occur in the body?
The birth control pill affects your hormone balance. It inhibits the release of the hormones LH and FSH—which are normally produced by the pituitary gland—and thus also prevents ovulation. In contrast, taking the pill keeps the levels of the hormones estrogen and progesterone very steady, mimicking the conditions during the luteal phase.
This phase actually begins after ovulation. The pill suppresses the natural interplay of hormones that trigger various processes in the cycle. So the body isn’t tricked into thinking it’s pregnant. Instead, it remains in a state that closely resembles the luteal phase. Your body therefore “thinks” that ovulation has already taken place. In a regular cycle, a so-called corpus luteum would form after ovulation; this is responsible, among other things, for the production of progesterone, which in turn influences your cycle. The pill also prevents your uterine lining from building up properly. In addition, the hormones in the pill alter the viscosity of cervical mucus. It becomes thicker, making it impermeable to sperm—which is why vaginal dryness is a common side effect of the pill. However, cervical mucus is also an important factor in fertility, as it helps sperm survive longer in the vaginal environment.
If you take a birth control pill that involves a one-week break from taking it, you’ll experience bleeding during that break. This bleeding has nothing to do with a real menstrual period; rather, it’s withdrawal bleeding. It occurs because the artificial hormone level, which was maintained by the pill for three weeks, suddenly drops.
When will ovulation occur again?
You’re probably wondering when you’ll start ovulating again after you stop taking the pill. Unfortunately, there’s no one-size-fits-all answer to this question, since every body and every cycle reacts differently to stopping the pill. However, a study (2002) found that two-thirds of the participants ovulated during their first cycle after stopping the pill. This means that the majority of women experienced a “normal” cycle with menstruation. Nevertheless, your cycle may be longer, and your period may come a little later than you’re used to. Since your body first needs to readjust, it’s also possible to have a cycle without ovulation—and therefore without a period—at first. However, the absence of a period is reversible. If you’re still concerned, or if you don’t ovulate for an extended period of time, it’s advisable to consult your gynecologist.
Are you thinking about stopping the pill but unsure how you can use birth control safely and without compromises in the future? We have just the thing for you. trackle helps you practice safe, hormone-free birth control. With the help of the cycle tracker, you can reliably track your basal body temperature. By entering your cervical mucus quality into the app designed for this purpose, you can identify which days you’re fertile and which you’re not.
