I have searched and found no information but wondered if anybody had knowledge of Estrelle? I have changed from Estradot 100mcg and utrogestan to Estrelle as the patches kept coming off and I had an early period last month. I am now on Estrelle 1mg and on day 16 of tablets and day 21 of my cycle and I am bleeding again (don’t start the green tablets until tomorrow). I’m not sure if I just carry on with the pack as normal or if I need to speak to the doctor again. Last month my period arrived day 21 and lasted for 7 days (normally arrives between day 26 and 27 and only for 3 days). I am aware that changing meds can affect periods but I have PTSD from a placenta previa complication and unexpected and prolonged, heavy bleeding really affects me mentally so I need to get my head around it.
