I've been on the pill for 3 months and I have skipped the placebo pills since the first month. I had unprotected sex for the first time a week before I was due to take the placebo pills (which I was going to take anyway) and a couple days later I started having a brown discharge and it slowly went redder and sometimes has thick bits in it. I am now on the placebo pills and I still have it (now a week after it started) Before going on the pill my periods were 3 days long and very light. What/why is this and could I be pregnant. I know bleeding does not mean I am pregnant but is it just a coincidence that I started bleeding two days after having unprotected sex for the first time since being on the pill? Thanks
