I have been taking tri-sprintec for around a year and never had any problems at least like this. I normally get brown didcharge and the start of my period 2 days after the first placebo. This month however I have had a consistently thick light brown mucous like discharge. I took my last real pill yesterday and had dark brown clotted discharge. I haven't missed any pills I normally take them at around the same time however this past week I started takes taking them slightly earlier than usual the end of the week I took them much later than normal. I don't think this is related but just in case I was playing soccer yesterday and end up getting hit in that area more than once very hard. Should I be concerned...could I be pregnant? Is this normal?
