Woman’s monthly period cycle and pregnancy

By | February 23, 2021

Getting pregnant is all about timing. You want to make sure the conditions are right for egg and sperm to meet. Your menstrual cycle can give you clues about when your body is ready to start the process.

The first step is to learn the days when you’re most fertile. Most women have a 28-day menstrual cycle. That means you have about 6 days each month when you can get pregnant. That includes the day that one of your ovaries releases an egg, called ovulation, and the 5 days before. Having sex within that window is key. You can’t get pregnant without ovulation, and tracking your monthly periods is one way to get familiar with your body’s fertility.

To figure it out, you’ll need to chart your menstrual cycle and record how long it lasts. Day 1 is the first day of your period. Since the length of your cycle can vary slightly from month to month, it’s best to keep track for a few months.

Once you have an average, subtract 18 days from the length of your shortest cycle. This is the first day you’re likely to be fertile. Next, subtract 11 days from the length of your longest cycle. This is the last day you’re likely to be fertile. Having sex between those two dates will give you the best shot at getting pregnant.

Check Your Basal Body Temperature (BBT)

It’s also a good idea to pay attention to the signs that your body is ready to ovulate. Checking your basal body temperature (BBT) is one way to do this.

The BBT is your temperature first thing in the morning. Just after you ovulate, it rises slightly — sometimes by less than a degree — and stays higher until your period starts. If you record your temperature every day, you can spot the subtle changes that mean one of your ovaries has released an egg.
