Hello, I ve been prescribed norethisterone, but I ve seen some pretty bad side affects and it s putting me off taking them. People have said they had twice the pain after taking them and there period was all over the place...my doctor didn t explain any of this. Is there anything else I could take to delay my period but not being the contraceptive pill or anything like that as I m not sexually active? I just need it to stop whilst I m on holiday.
