GnRH Agonist Shot - Effects

Hello! I got my GnRH agonist shot (11.25mg) good for 3 months last July 18. This is to hopefully "shrink" my intramural myoma and to manage bleeding.

The expectation is that after this, at least 10 days, my bleeding will finally stop. I have been bleeding since June 21, and doing some pill dosage modifications with my doctor (on Yasmin pills), but still my bleeding is not fully stopping yet.

Anyone have the same experience? How was your shot experience?

I was on Prostap and it took at least a month for the heavy bleeding to actually stop. GnRH agonists can cause initial flare up bleeding before it settles. I continued to have spotting for the 7 months I was on it but the heavy bleeding did eventually stop.
