How to use the Clomid ovulation calculator?

Our Clomid pregnancy calculator is an extremely simple tool - all you need to do is follow two simple steps:

  1. Enter the first day of your Clomid treatment.
  2. Choose the whole duration of your Clomid treatment.

Our calculator will show you your expected ovulation day as well as your estimated fertility window (that's when you should have intercourse in order to conceive).

🌟 Good luck - you're on the best way to success! Soon you'll need all of these tools:

What is Clomid, and how does it work?

Clomid (Clomiphene citrate) is a drug taken orally and is used in treatment of infertility. It is especially recommended for women with impaired ovulation processes (e.g., those suffering from PCOS).

💡 Women taking Clomid are more prone to have multiple pregnancies (especially twins).

Clomid blocks the effects of estrogens, the female sex hormones that regulate fertility. This drug tricks the body into thinking that there's not enough estrogens, leading to an increase in their production, which leads to ovulation and implanatation.

What are the best days to take Clomid for success?

Clomid treatment should be started during the first 5 days of a menstrual cycle. The therapy usually lasts another 5 days. You can have three consecutive treatment cycles. The dose may be increased in case of treatment failure.

How soon do you ovulate after taking Clomid?

The Clomid ovulation day approximately happens one week after the last dose of Clomiphene citrate.

When to have sex on Clomid?

Since the sperm can live up to 7 days inside the female reproductive system, the ovulation day varies from woman to women, and the egg lives for 24 h after its release, the best time to have the intercourse is actually a range of a few days. You can start trying the day after the last dose of Clomid, and increase frequency with which you have sex as the estimated Clomid ovulation gets closer (follow the fertility window calculated with our tool on the left).

Calculate it yourself - when will I ovulate on Clomid?

In this section, we'll explain how we created our Clomid calculator. In order to do that, we need to take a closer look at a typical Clomid calendar that starts on the first day of your menstrual cycle:

  • First day - First day of your menstrual cycle;
  • Fourth day - First dose of Clomid (usually 50 mg);
  • Eight day - Last dose of Clomid (5 doses taken altogether);
  • Fifteenth day - Expected ovulation day; and
  • Twenty-fourth day - Expected implantation day.

Now you can see why we used the following equation:

Ovulation = Treatment start + Treatment duration + 7 days

  • A Clomid cycle's length is usually different than a regular menstrual cycle, even though the Clomid ovulation day is expected to be close to a natural ovulation day during a regular 28-days cycle.

  • The Clomid ovulation calculator for a boy is the same as for a girl - once the baby has been conceived it cannot change its gender. The chances for conceiving a boy or a girl are always 50/50.
