When will you ovulate?

Ovulation usually happens between 5 and 9 days after taking the last pill of Clomid. Calculate the expected date of ovulation as well as the best days to have sex based on the first date you started taking Clomid with our clomid ovulation calculator.

How does Clomid cause you to ovulate?

Clomid is a synthetic chemical that induces ovulation by fooling your body into believing that there is less estrogen. This leads to increased production of a hormone called GnRH, causing the pituitary to pump out more of another hormone called FSH and LH, thus inducing ovulation. Clomid is very powerful and induces ovulation in over 50% of all women who take it.

(If you're not using Clomid, please use our standard ovulation calculator.) 

Clomid works well for many women but it does come with side effects like headaches, mood swings, hot flashes, weight gain, etc. It is usually given as a pill once a day for 5 days. The typical starting dosage of Clomid is 50 mg/day for 5 days, and it can be increased monthly by 50 mg a day. The first pill of Clomid is usually started 2 to 5 days after the first day of your menstrual bleeding (cycle day 2-5) and ovulation usually happens 5-9 days after the last dose of Clomid.

If you don’t bleed, and after pregnancy has been excluded, bleeding can be started by taking progesterone.

How soon after taking Clomid are you fertile?

Clomid is a synthetic chemical whose chemical name is Clomiphene citrate. It is not a fertility drug per se and is given only to induce ovulation by fooling your body into believing that there is less estrogen. Clomid is usually given for 5 days, starting on cycle days 3-5, and most women will usually ovulate 5-9 days after the last dose of Clomid.

How do you know that Clomid worked and you will ovulate?

So how do you know that Clomid has done its job? There is a clear-cut way to determine its efficacy: if you ovulate while on Clomid, that means it worked. If you did not ovulate, it did not work. Yes, it's that simple. 

How long does it take to ovulate after taking Clomid?

For women that do not ovulate on their own, the average day that ovulation occurs is about 8 to 10 days after completing a 5-day course of Clomid.

That means that a woman taking Clomid on days 5-9 will often ovulate on about day 16-20 of the cycle.

However, there is a significant variation in how long it takes to ovulate using Clomid. Some women will ovulate much later — as late as two or three weeks after the last clomiphene tablet.
