I was supposed to take Letrozole from day 3 to day 7 of my cycle, but my cycle was irregular, so I didn't take it at the right time. Will it still be effective?

It is difficult to determine if Letrozole will be effective if not taken at the correct time during the menstrual cycle. It is important to take the medication at the specified time to maximize the chances of ovulation. If your menstrual cycle is irregular, it may be more challenging to take the medication consistently. It is recommended to consult with your healthcare provider to determine the best course of action. If you experience persistent or heavy bleeding, it is advisable to speak to your pharmacist for guidance on whether to see your doctor sooner.
