I've been taking birth control for the past two years almost and I've never had a problem with my period on the pill. I've taken it religiously, since I started. But I'm on the 5th day of my placebo pills and I haven't gotten my period only two small brownish blood clots and mild cramps. I am not sure what to do should I wait until 5 days before my next period and then take a pregnancy exam? I have no idea as to what to do first. Is this normal? Should I make an appt. asap to see my doctor?
