I plan to start taking Centchroman this month once I start my next period. The problem is that in the meantime, I had a condom break on me during sex and I took a morning after pill last night (Next Choice). I've previously taken a morning after pill and at that time, I had a few days of spotting/bleeding a week after taking the pill, and then a normal period approximately two weeks after that. Assuming this happens again, that I start spotting/bleeding next week from the morning after pill, and that its not yet my normal period, should I start the Centchroman when I start spotting or do I wait until I get my normal period? Any advice would be much appreciated!
