When you’re ready to start trying for a baby, there are a lot of things to think about—and one of the biggest questions is, “When is the best time to have sex to get pregnant?” After years of trying to prevent pregnancy, shifting to the goal of conception can leave many people feeling confused and overwhelmed. But the good news is, timing is key, and understanding your fertility window can make a world of difference.

In this blog, we’ll break down the facts about timing, ovulation, sperm survival, and bust some common myths surrounding sex and conception. So let’s dive in and get you on the right path!

1. When Should You Have Sex for the Best Chance of Pregnancy?

One of the most common questions when trying to get pregnant is, “When should we have sex?” The short answer is: the best time to have sex is when you’re ovulating. But ovulation is just one part of the equation. Here’s what you need to know about timing.

Sperm can live in the female reproductive system for up to five days, which means that having sperm ready before the egg is released can increase your chances of conception. The egg, however, only lives for about 24 hours after it’s released, which means that if you wait too long, the egg may no longer be viable for fertilization.

2. Understanding Ovulation and Your Fertile Window

Your fertile window is the time during your menstrual cycle when pregnancy is most likely to happen. For most people, this window is about five days before ovulation and the day of ovulation itself. If your menstrual cycle is regular and predictable, it’s easier to estimate when you will ovulate. Here’s how:

Cycle Length: Day 1 is the first day of your period. If you have a 28-day cycle, ovulation typically occurs around Day 14.
Tracking Ovulation: The best way to track ovulation is to use ovulation predictor kits (OPKs). These kits test for a hormone surge that occurs right before ovulation. Once you get a positive test result, it means you’re about to ovulate, so have sex immediately.

Another way to track ovulation is by measuring basal body temperature (BBT). After ovulation, your body temperature rises slightly, and this can help you pinpoint when you’ve ovulated. Additionally, observing cervical mucus can also help. When you’re ovulating, your cervical mucus will be stretchy and clear, similar to raw egg whites.

3. How Often Should You Have Sex?

Some people wonder whether they should have sex every day or every other day while trying to conceive. The good news is you don’t have to have sex every single day! In fact, every other day is often the best approach. This allows sperm to build up in the reproductive tract, ensuring there’s plenty of sperm ready when the egg is released.

However, if you’re tracking ovulation and know you’re about to ovulate, having sex the day before ovulation and on the day of ovulation is a great strategy. Either way, having sex a few times during your fertile window will increase your chances of conception.

4. Does Sex Position Matter?

It’s a common myth that certain positions can increase the chances of getting pregnant. In reality, the position during intercourse doesn’t matter when it comes to conception. The key factor is getting sperm into the vagina, where it can then swim up into the cervix.

Some people believe that the woman should keep her legs in the air or lie down afterward, but there’s no evidence to support that this increases the chances of pregnancy. Sperm are fast swimmers and don’t need extra time in the vaginal canal to reach the egg.

Note: Female orgasm can help facilitate sperm movement, but it’s not a must-have for conception to occur. The primary goal is to ensure sperm gets to the right place.

5. Do You Need Lubricant?

There’s a growing trend of fertility-friendly lubricants on the market, claiming to enhance fertility and improve the chances of conception. While it’s true that some lubricants may harm sperm, you don’t necessarily need them. If you don’t need lubrication for comfort during sex, it’s best to skip it altogether.

If you do need a lubricant, choose one that is sperm-friendly. Many water-based lubricants are designed to be less harmful to sperm and can be a safer option during the conception process.

6. Can Certain Practices Help or Hurt Your Chances?

You may have heard of various methods people use to help increase fertility, such as placing a diaphragm in the vagina after sex to keep sperm closer to the cervix or lying down with legs elevated. However, these practices don’t have a proven effect on improving your chances of pregnancy.

The most important thing is to relax, track your cycle, and focus on having regular, timed intercourse. There’s no need to overcomplicate things—just keep things natural and simple!

7. Should You Be Concerned if It Doesn’t Happen Right Away?

Trying to conceive can sometimes take longer than expected. On average, it takes most healthy couples six months to a year to get pregnant. If you’re not getting pregnant right away, don’t get discouraged. However, if you’ve been trying for a year or more without success, it may be worth speaking with a healthcare provider to explore other factors that could be affecting fertility.
