I am facing a problem with the periods. Last month, November, I had it twice within 5 days of gap. 1st one finished on 5th November (flow was normal) and then started again on 10th November (flow was less), (last month I donated blood too). This month my periods started on 1st and ended on 6th (the flow was less than normal), and right now I am bleeding again (with a very very less flow). Last month I used "Unwanted 72" after unprotected sex. But this time I didn't. Isn't it due to the side effects of Unwanted 72? But I have used it many a times, nothing like this happened before. Please help me with this.
