My period has always been really irregular so I have been on a BC pill for 3 months. On the last day of my last period I messed around with my boyfriend. It is now a month later, and my "period" was 3 days late--If you can consider 2-3 days of clots a period. After the clots, I had vaginal dryness for a couple days, and now I have thick, clumps of discharge. Here's my question: was that a period, or should I be concerned about something serious?
