Can I advance my period for upcoming travel?

Based on your symptoms, it is improbable that you are pregnant because you have taken three negative UPTs and your last intercourse was in November. Your period time may be different because of PCOD. That's why your gynecologist diagnosed you with PCOD. As long as you take the drug recommended by your gynecologist, norethindrone acetate, according to the dose and monitoring for adverse effects, it is ok. But, if the backaches and tiredness continue, then consult your gynecologist again
 

Give yourself time to heal and avoid activities that worsen the pain. Over the counter pain relief like also can help but take only as if prescribed by a doctor. Apply cold compress to reduce swelling.

Hormonal contraceptives do affect your menstrual cycle. Also if your pregnancy test is negative then the period delay can be due to stress, changes in weight, or certain medications.

Hormonal imbalance or other factors can cause period problems and a gynecologist should be consulted for an accurate assessment and treatment. Coxicam, meloxicam, zune, esomeprazole, ms. futine and fluoxetine as HCI USP are out of the question for menstrual issues. I'd suggest going to an expert in gynecology for the management of period problems.
 

Late periods and vaginal dryness can have many causes of which stress, hormonal imbalances, and infections are included. Kindly seek medical help if you experience any uneasiness or unusual symptoms.
