Heavy bleeding days after Zoladex??

Hello all I have "suspected" endometriosis, however one of my drs thinks I have it but I am not diagnosed and no one seems to have wanted to give me the formal diagnosis

I have been on the mirena coil for about 4 years now and havent had any periods since.

Anyway In late 24 / early 25 I was given a trial of Zoladex to see if it eases my symptoms for 3 months which if it did, he said it pretty much guarantees its have some from of endo/ andeomyosis or pcos etc.

The zoladex worked, I got the typical menopause like symptoms for a few months then when it wore off I went back to my "normal"

Fast forward to earlier this week, I was given another trial of Zoladex, the injections was given on I think Tuesday?

Ive been fine since but today I noticed I was getting some random cramping. Thought oh I might just need the toilet, kinda reminded me more of having the shits than period cramping pain wise. But didnt need the loo so went back to work as normal, but kept a hot water bottle on me all day.

Pain has progressively gotten worse through the day and has spread round to my back, but nothing out of the ordinary of pain, but just felt off? Like not normal. Just sorta cracked on with my day as usual.

I get home at 4pm and think oh I need a wee, so Will pop to the loo.

My pants were flooded with blood, hands covered when I pull them down and I am like where has this come from?? I went to the toilet maybe 30-45 mins prior and it wasnt like this?

The tissue was also covered in blood, some clots and a thick snot like discharge??

It calmed down about an hour after this but like has anyone ever gotten anything like this after Zoladex?? Im unsure if it was coming on all day and just happened after I noticed it going for a pee, or if it came on so sudden because I tried to go for a poo earlier (no excessive pushing, just tried really quickly and realised I didnt need to as the cramps weren't the same when I tried, so didn't bother keep trying)
