Hi doc have started taking Ovuloc ld tablets, and I know that I have to take it for 21 days and then stop for a week and start again from the day 1 of the next period. But my worries is I usually have cycles in every 25 days. So after taking this pills for 21 days. Shall I wait 1 week to start again with a new course of Ovuloc ld or shall I start the new course when I get my periods? In this case I have to stop medicine for only 3 days, will it not harm me for overdose.
