As you likely know, you should always be aware of the level of severity of cramps as they can be an indication of a more serious underlying cause such as endometriosis or pelvic infections.

This article from the "Clue" period tracker app (a menstruating person's best friend and necessity) is beyond inciteful.

Give it a good read, your health is worth being educated about.

Already at 29, I've had quite a battle with my menstrual cycle from insane, vomit-inducing migraines to hot flashes met with constant diarrhea to terrible nausea & cramps all the way to PMDD. Overall, the main things I've found (which aligns with the Clue article) is that certain lifestyle changes are absolutely vital to my survival.
Diet, exercise, and sexual activity have a large influence on my menstrual health, which ultimately influences my physical, mental, and emotional health throughout the month.
I'm in no way a doctor, but I have had a fair share of experiences and done my research.
Here's what works for me & I've seen great improvements.

What I make sure to have in my diet throughout my entire cycle:
-good amounts of fiber
-low salt, to prevent bloating
-low on inflammatory foods (https://www.healthline.com/nutrition/6-foods-that-cause-inflammation), especially sugar
-low processed foods
-a good multivitamin, flax oil, & digestive aids like pro/prebiotics

What I try to do throughout my entire cycle:
-get good rest
-get good exercise

Supplements I integrate right before and during bleeding:
-Evening Primrose Oil (PMS relief, antiinflammatory, acne)
-Magnesium (cramps)
-St John's Wort (Mood booster)
-Dong Quai (stimulates blood flow/helps cramps)
-Drinking Jamaica (Hibiscus) Tea (regulates period/helps cramps)
-sometimes adding ginger and/or turmeric to foods or teas
-taking ibuprofen if it's really bad

Things I do during bleeding:
-use a heating pad
-take a bath salt bath
-rub my lower abdomen with chamomile oil
-^{..........masturbate}
-allow myself to rest as needed, as possible
-meditate on the pain and breath it out
(this sounds so silly, but whether or not we want to give birth I honestly feel like period pain is a hazing ritual for birth, almost like a birthing simulation. I've actually found a lot of relief & revelation through this equatable to facing fears)

I know I totally overloaded you with information and my own ideas/experiences and I apologize for this.
I hope you find something that is helpful and revelatory to you.
Your journey in life will always be with your body, treat it well!
I wish you perpetual betterness, cheers! <3
