Maximize Your Chances of Conception

To increase your chances of getting pregnant, aim to have intercourse regularly throughout your fertile window, which includes the five days before ovulation and the day of ovulation itself. Sperm can survive inside a woman's body for up to five days, so starting early can increase your likelihood of conception.

Other Methods for Spotting Your Signs Of Ovulation

If you are wondering how to tell when you're most fertile, there are some key signs you can watch out for, such as

  • Cervical Mucus Changes
  • Basal Body Temperature

Additional Tips

  • Regular Sex: Aim for regular intercourse, especially during your fertile window.
  • Healthy Lifestyle: Maintain a healthy weight, de-stress, and manage any medical conditions.
  • Partner's Health: Encourage your partner to maintain a healthy lifestyle as well, as male fertility plays a significant role in conception.
