Trying to get pregnant can be a frustrating process for some people, while for others, it is could be as easy as ABC. Knowing when your ovulation occurs is the key to this, all other things being equal. The following gives you an idea on why you need to monitor your ovulation.
1. Your cycle may change from month to month.
The length of a normal menstrual cycle varies from 28 to about 36 days.
These variations are based on a number of factors, including your natural body
rhythms, stress levels, and weight gain or loss. Ironically, the stress of
trying to conceive may throw your cycles off kilter. Monitoring your cycle
through ovulation predictor kits (OPKs), charting basal body temperature (BBT),
and/or examining cervical mucus can greatly increase your odds of becoming
pregnant during a particular cycle.
2. All cycles are not created equal.
Even if you menstruate every 28 days without fail (and few women do),
there's no guarantee that you'll ovulate exactly midway through your cycle. In
fact, women with 28-day cycles may ovulate anywhere from day 12 to day 16 — or,
occasionally, not at all.
3. You're only fertile for 24 hours.
Once you ovulate, there's a small window of opportunity — roughly 24
hours — before the egg degenerates and is reabsorbed into your body.
Fertilization must occur within this period. Yet sperm, which live for three to
four days, can take eight hours or more to swim up the cervix and rendezvous
with the waiting egg (like men, they're not always punctual!). Monitoring your
cycle helps you predict when you're going to ovulate at least 24 to 36 hours in
advance, giving you more time to get the sperm started on their journey.
4. You may have a short luteal phase.
The second half of your menstrual cycle — between the day you ovulate
and your next period — is called the luteal phase. Although the normal length
of this phase is 12 to 16 days, for some women it is much shorter. A fertilized
egg needs 10 days to reach the uterus and implant. If your luteal phase is
shorter than this, you will need drug therapy to increase it before you can
successfully get pregnant.
5. Cervical mucus may help — or hinder.
Cervical mucus (the vaginal discharge that accompanies ovulation) varies
in consistency and appearance, from thick and cloudy to clear and elastic. In
order to provide a fertile environment for the sperm, mucus should have the
consistency of egg whites: clear, slippery, and slightly stretchy. It's
important to monitor your cervical mucus around the time you ovulate and plan
intercourse accordingly. Otherwise, even if you ovulate right on schedule, the
sperm might be unable to reach the egg in time.
