"Annuale"s not for everyone. Do not take if you are using MAIO Inhibitors or if your occupation requires you to operate heavy machinery. Do not take Annuale if you ever plan to become pregnant, as it may turn your baby into a firemonster. In the days around your period, you may develop a leathery tail. Annuale may cause you to develop a second vagina. Notify authorities in your town when your period is imminent as they may want to incarcerate you pre-emptively like a wolfman."
The above "ad" is from a Saturday Night Live skit, imagining what a once-a-year period would be like. No offense Tina Fey (who IMHO is generally awesome), it does not have to be this way.
Heavy and/or irregular periods are the bread and butter of a gynecologist"s practice. It used to be that there was one solution: hysterectomy. But thank God (and medicine) that there are many newer options.
Before exploring these options, you should be evaluated by an experienced gynecologist to rule-out common and often correctable causes of heavy bleeding. If you are an adolescent or teen with very heavy periods, your provider may want to make sure that you do not have a blood-clotting problem. There is a disorder called von Willebrand Disease (VWD) that affects approximately 1% of the population, but is in roughly 15% of women with very heavy periods. Easy bruising and bleeding gums are other red flags that can lead to this diagnosis.
If you are an adult and your bleeding is gradually getting heavier, you may have a polyp in your uterus or fibroids. Your provider may want to do an ultrasound or if your bleeding is at all irregular, a biopsy of the lining of your uterus.
Heavy and painful periods affect so many women. They can impact work, relationships and sense of well-being, and possibly cost a small fortune in hygiene producQuoted From: https://www.evergreengyn.com/blog/outta-control-periods-and-what-to-do-about-them
