FET prep #2

Had a saline US on Monday no bleeding, mild cramping day of then gone. Big gush of blood today ( Wednesday) and hasn’t stopped yet. My period was January 30th did saline on day 12 of cycle. I called the clinic, but they say it’s normal after a saline? I’m hopeful it’s my period again and we can push up my FET, but I’m not sure. Anyone have this much bleeding 2 days after this procedure? I can’t remember what it was like the first time I had this done. I don’t recall bleeding like this. I have PCOS so my cycles are nuts.
