Clomid is a synthetic chemical which induces ovulation by technically ‘fooling’ the body into believing that there is less estrogen. This leads to an 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 extremely potent and induces ovulation in over 50% of all women who take it. Clomid works well for many women but it does come with its own share of side effects like headaches, mood swings, hot flashes, weight gain, etc. It is usually prescribed 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 the menstrual bleeding (cycle day 2-5) and ovulation usually happens 5-9 days after the last dose of Clomid.
There is no one particular day that all women will ovulate after taking clomid. Most women will ovulate 7 to 10 days after they take their last Clomid pill. Depending on the Clomid protocol one is on, implies the time one should be having sex every day or every other day starting on Day 11 through Day 21 of the respective cycle. Some women will ovulate much later, as late as two or three weeks after the last clomiphene tablet.
According to some doctors taking Clomid on Days 3, 4, 5, 6, and 7 of the cycle is a good idea, while others recommend taking Clomid on Days 5, 6, 7, 8, and 9.
If one is on the Day 3 to 7 protocol, this would mean that she most likely to ovulate (on average) sometime between Day 14 and Day 17 of the cycle. In order to conceive, one would want to have sexual intercourse before she ovulates. So, one would just want to have sex every day or every other day starting on Day 11 and ending on Day 18.
On the other hand, if one is prescribed clomid on days 5 to 9, she is most likely to ovulate (on average) between Day 16 and 19. In this case, she would want to start having sex every day or every other day starting on Day 13 through Day 21.
As mentioned earlier, these are mere averages and generalised ideas to help one have an estimate of the days when one is most likely to ovulate. It is very well possible that one would ovulate earlier or later than the average. This means that one could theoretically miss one’s most fertile time if one starts having sex too early or too late.
Sometimes a clomic injection is also prescribed by doctors. The most common injectable medication is the hormone human chorionic gonadotropin (hCG). This is sometimes called a trigger shot because it triggers ovulation to occur within 24 to 48 hours after injection. This implies that the most fertile day of the cycle will be the day of the trigger shot injection. Unless otherwise notified by the doctor, one should start having sex on the day of the trigger shot. To optimize one’s odds of conception, one should keep having sex every day for the next three days.
In order to track the resulting ovulation process after taking clomid, one’s bet to tell whether one is ovulating or not would be to use an ovulation predictor test. If one has never tried an ovulation predictor test (OPK), they work a lot like pregnancy tests where one has to urinate on a stick, and the test will indicate whether one is in the fertile window or not.
One can start taking the OPKs the day after she finishes taking Clomid pills. She should keep taking the tests until she gets a positive result. A positive result indicates that one is nearing ovulation and should have sex. One should start having sex every day until the OPKs are no longer positive.
