Here’s When to Get Pregnant to Have a Baby in May

Hoping for a due date in the month of May? Learn how to calculate the best days to conceive for a May baby.


Blooming flowers, plenty of sunshine, and Mother’s Day – who wouldn’t want to have a baby in May? Conception can be unpredictable and happen when you least expect it, but May always ends up being one of the most popular months to aim for having a baby.

To increase your odds of delivering in May, you need to do a few calculations based on your average cycle length, suspected ovulation date, and what days you’re most fertile.

Most women who conceive in August or early September will have a May baby.

What the Experts Say

“If your cycle is twenty-one days, you may be ovulating around day seven of your cycle. The concern with shorter cycles is whether you are going to build enough uterine lining to be receptive to implantation, having just shed it in menstruation. If your cycles are longer than thirty-five days, you may not be ovulating often enough during the year to be fertile. If you think this is true for you, talk to your doctor.”

“To calculate when you are ovulating technically you count 14 days backwards from the start of your period to know when you ovulate. However as this time would have gone you need to count up so you will ovulate between 11-17 days after the first day of your period, so count the day after your period as day 1 and count up to 11. This is the best time to start trying.”

“No matter how you try to time the arrival of your baby or you think you can predict the sex of your baby, sometimes it just doesn’t happen that way. It could take longer than you expected for no reason, or you may have a girl and everyone in the family had a boy. It is just nature’s way.”

“Once you’ve said yes to another baby the next decision is when to start trying. There’s no perfect time to have another baby, and if you wait until the circumstances are just right, you might never do it. Even with careful planning, you can’t always control when conception happens.”

“Learning about your individual fertility cycle is a valuable exercise for a number of reasons. First, better timing of intercourse dramatically improves the chances of conception. Second, it allows a woman some feeling of continuing control over events: it is all too easy to get swept away by the apparent success of medical intervention when handing over this reasonability may not, in the long term, be the most beneficial option.”

Timing Your Pregnancy

Getting pregnant on cue isn’t easy. At age 35, most women have a 15 to 20 percent chance of getting pregnant in a given month, according to Parents Magazine. Your chances of pregnancy go up when you’re younger and go down as you get older. Not many couples conceive exactly when they want to.

Knowing when you ovulate can help. A woman typically ovulates about 14 days before her menstrual cycle begins. This is her most fertile time of the month. If you have an average 28-day-cycle, you’ll likely ovulate around day 14.

However, if you have a longer 36-day-cycle, you won’t ovulate until around day 22. Having intercourse during the three to four day period around your fertile time is your best bet for getting pregnant.

Goin’ for it: the Right Amount of Sex

If you’re adamant that you want to deliver in May, you’ll want to engage in plenty of intercourse in the month of August. However, too much is not good either. You still want it to be fun and not become a chore.

You’re more likely to get pregnant if you have sex daily or every other day. If having sex daily isn’t an option, make sure that when you do have sex it’s during your most fertile time.

You should opt for a minimum of two to three days a week starting at the end of your period, according to Mayo Clinic.

How to Boost Your Odds of Conception

Getting pregnant is harder than it looks. Increase your odds of conceiving in May by following a few simple tips.

  • Start taking prenatal vitamins before you get pregnant to fill any nutritional gaps.
  • Avoid the use of lubricants which can negatively affect sperm mobility.
  • Cut back on your caffeine intake. You should aim for no more than 200 to 300 milligrams (mg) when trying to conceive, according to Baby Center.
  • Keep alcohol consumption to a minimum and try your best to relax.
  • Maintain a healthy exercise regimen but don’t exercise too strenuously.
  • Smoking can reduce sperm quality. Encourage your guy to stop the cigarette habit.
  • Get a handle on your chronic stress or anxiety issues. High stress levels can effect ovulation.

While it’s not an exact science, it is possible to time your intercourse so that you have a baby in May. However, the getting pregnant part is not always easy. By tracking ovulation and boosting your fertility, you can significantly increase your odds of having a springtime baby.
