Letrozole is a drug that can cause your body to ovulate. Therefore, it is going to be easier for you to become pregnant. It is common practice to start taking it on days 3-7 of your period.

Always consult a doctor before using tablets to change your period. The menstrual cycle is a natural biological process, and altering it with pills can harm your health. While it’s understandable to want to adjust your period for events like a cousin’s wedding, it’s important to let your body follow its natural cycle whenever possible.

Periods can be missed due to pregnancy, or other medical conditions. Factors like stress and weight fluctuations can disrupt hormonal balance while certain medications or medical conditions can also affect menstrual regularity. 

Urine infections and bladder troubles often cause pelvic pain and frequent urination. Common germs invade urinary tract parts, like the bladder or kidne­ys, sparking UTI. But irritants -- foods, drinks -- may also disturb the bladder, leading to the same issue­s. Hydrating well and dodging irritants helps relie­ve symptoms. However, see doctor for prope­r assessment and cure.
