I have been on Familon since last 4 months to treat Endometriosis. I had to start my next 21 days cycle of Familon after 7 days of the last Familon cycle. But I forgot to take it on my scheduled 8th day and remember it on the next day approx. at the time of my 2nd dose. Should I take two pills at the same time, or should I take the missed pill in the morning and regular pill in the evening?
