There are ways.: Speak to your GYN doctor, you can modify your hormonal balance with birth control pills. For example, your doctor could give you progesterone only pills in a higher dose for additional days close to your usual cycle start and delay the onset of your menses for a week. There are methods to cause it to start early. As suggested, have a clear conversation with your gyn doc and work together.
