I m on Microgyson 30 (combined pill) & I took the 21 days tablets at the same time for all the days. But then I wanted to move onto my next set and took them for four more days due to a holiday. I then thought I d take my 7day break mid second set but after reading online I worried that it might be more Effective to take the tablets until the end of the second set before then taking the 7 day break. With this being the case I took the tablet from yday and today, this evening. Is it best to finish the second set instead of midway? I m thinking on the effectiveness of the contraceptive. Also, once I finish the second set and take the 7 day break, will it erase this confusion for when I begin again?
