Anyone on Cerazette/have been

I’ve been on Cerazette for 6 weeks now. The first maybe 2/3 weeks I had no problems with it. But for the past 3 weeks ish I’ve been feeling sick, suffering with headaches, been way more tired than usual and every now and then I seem to have no appetite. I just generally don’t feel my self and just feel shitty all the time. Has anyone else felt like this while on this pill? Considering changing bc.
