extreme period pain - does this sound like endo?

[lockdownmummax]

looking for some advice,

i have 2 children, always had period cramps however after my first born they got more severe, and after my second born my periods have just been awful
I'm 24 btw

so my symptoms are,
Approx 3 days before periods
flank pain like a dull ache
Spotting brown blood
Some pelvic pain which is minimum

during periods
lower back feels very sore like a pressure on my back, travels down my bum cheeks
Pelvic pain
Intense cramps
and I feel like I have a heavy weight sitting inside my lady bits waiting to fall out the pressure is intense!
the pain sometimes has me bent over in pain, I think I have a high pain tolerance and can usually deal with pain but this is terrible
What is this?? i have been to my GP who advised me to go on the mini pill but offered no testing

Came just to say i have what u have and its not endo. Back and forwards to doctors and nothing found yet.. but bother gp for a scan at least if u havent had one
Only way to see if its endo is theough surgery. I had mine this year and was pointless, nothing found. Better try coil or pill first before u go down this road.
