I recommend seeing a nutritionist ... A change of diet...
Cutting out certain foods that generally make endometriosis symptoms worse.
Cut saturated fats and bad foods
Water water water
I'm on my 4th day and I actually feel slightly better.... I'm 22 and not willing have injections that induce me in to the menopause!!! I still have at least 30 years in me. It's hard to change diet when you have been so use to eating and drinking what you want when you want.... But if you want to not be in pain at least try it.
Hope this helps guys!!!!
