On Wednesday I went on a camping trip and forgot to pack my BCPs with me, causing me to miss two days of my pills. As soon as I got back on Friday I took two pills, and then two the next day. Throughout this time, I've been having breakthrough bleeding, which started on Friday. I had unprotected sex with my boyfriend on Saturday because I thought I stopped bleeding, and no blood was present. Afterwards, I noticed that I was bleeding again, but this time the blood was more red than it was. What does this mean?
