I missed two birth control pills in the third week of my tri sprintec pack. I took the rest of the pills like normal but had my period that week instead of the next. I continued to have some brown discharge like you do when you are getting off your period. Now, I have some bleeding and the same brownish discharge. I am not experiencing any cramping at all. There isn't a lot, but I'm just wondering what is causing this? I'm not too worried, just looking for others opinions. Is this a result of the two missed pills and then continuing the pack like normal?
