This might be a dumb question, but can you get endometriosis at any time or is it something you’re born with? After having my daughter my periods made me feel sick, they were heavier and overall just not a good experience compared to before. I got the depo shot the first week of january and never renewed it in march. for the past few months (and after my daughter was born) i’ve had painful ovulation, feels like my uterus is filling up with air or water. I had my period this week, lasted about 2 days which never happens. and now i’m having really cramps back pain in my lower back and achy in my pelvic area
