Today is Oct 27 I had to get vaginal bleeding (side effect of the tablet) but I dint get it.I am worried about this.My doubt's are is it compulsory that after 1 week of intake of the tablet vaginal bleeding should occur. And approximately after the intake of tablet after how many days vaginal bleeding can occur , and what if the bleeding is not occurring what does this mean. And my other doubt is after how many days of having sex should pregnancy test be done to get correct result
