Can anyone help please? I took my Prostap injection yesterday (Wednesday) on day 21, but I started bleeding today (Thursday) at 6pm, even though my period wasn’t due for another week. Would tomorrow (Friday) count as day 1, and should I start my Estradiol (Evorel) patches on day 2 (Saturday), or wait for advice from my clinic? Has anyone else had a bleed straight away after Prostap? I wasn’t expecting it for another week, so now I’m worried I’ve got my dates wrong.
