My periods is on 1st november. I want to delay my periods so i am taking Ovral-L (levonorgestrel and ethinyl estradiol tablets) from 22nd October. I took this medicine for this purpose many time before but never feel the pre menstruation uneasiness. I have an important exam in 5th november so I can t take risk, so i started earlier. Please, tell me though I am taking this medicine is there any risk to get periods? Because i am feeling like my periods is may come, little pain in lower abdomen, irritation and and the other associated thinhs with menstruation.
