Buserelin trigger - when did you get your period

Katie

I had my egg retrieval on 18th using a buserelin trigger. I’ve experienced withdrawal bleeding over the last few days as expected but speaking with the nurse at the clinic she said to expect my period at the normal time. I even confirmed this by saying ‘what twice in a week?’ This seems pretty strange to me. Has anyone had any experience of using buserelin as a trigger? What was your cycle like after?
