Clomid Timing Planner
Clomiphene citrate is typically taken for 5 days early in the menstrual cycle. This calculator estimates the expected ovulation window and fertile days after treatment.
Most protocols start on day 3, 4, or 5.
Typical regimen: 5 consecutive days.
How to Use This Calculator
Record the first day of your recent period
This date anchors the cycle day count used for Clomid dosing and ovulation prediction.
Enter the prescribed start day and number of Clomid tablets
Most regimens start on cycle day 3, 4, or 5 and continue for 5 days.
Use the ovulation window for timing intercourse/insemination
Plan intercourse every 1–2 days during the fertile window or follow your provider's specific instructions.
Formula
Clomid dose dates: LMP date + (start day − 1) through + (start day + duration − 2)
Expected ovulation: 5–10 days after the last Clomid pill (common clinical window)
Fertile window: (Ovulation start − 2 days) through (Ovulation end + 1 day)
Next period (if not pregnant): LMP date + cycle length
Full Description
Clomiphene citrate stimulates ovulation by blocking estrogen receptors in the hypothalamus, prompting increased FSH and LH release. Ovulation typically occurs 5–10 days after the final dose. Individual response varies, so monitoring with mid-cycle ultrasounds or hormone testing offers greater precision. This calculator provides a planning framework for timed intercourse or intrauterine insemination (IUI) cycles when dedicated monitoring is not used.
Frequently Asked Questions
Should I use ovulation predictor kits (OPKs)?
Yes. OPKs can confirm LH surge timing and refine the fertile window during Clomid cycles.
What if ovulation doesn't occur?
Contact your clinician. They may adjust dosage, switch medications, or add monitoring to guide treatment.
Can I take Clomid without supervision?
Medical supervision is important to manage side effects, confirm ovulation, and minimize multiple pregnancy risk.
Does Clomid affect menstrual cycle length?
Some users experience shorter or longer luteal phases. Track cycles closely and report irregularities to your provider.
