I was just switched to a new birth control (Tricyclen-Lo) because on my old pill (Marvelon) I was getting my period near the end of my placebo pills and it would continue on into my new pack of pills. I just started my second row of pills on Sunday, but missed taking my Sunday pill resulting in me taking my Monday and Sunday pills together. Today (being Tuesday), when I went to wipe after peeing, I had blood on the toilet paper, along with a bit of clear fluid.

Is this normal? I always use protection on top of the pill so I don't think I'm pregnant. But, if this is a health risk I do want to know.
