On march 28th i had sex with my bf he didn't used a condom. Also that day was the start of my 9th pack of pills which I started it on time. Last week on Tuesday I notice brown spotting on my underwear I continue to get spotting Wednesday that was darker then Tuesday I spotted again Thursday, Friday Saturday and today. When I wipe my self sometime it looks darker and other times it looks light or nothing comes out. Sometimes i think it will end and it doesn't. I started placebos yesterday and haven't gotten my period. I am cramping also off an on. Will I get my period or should I worry?
