Why????

Be

I've been on birth control for a very long time. I haven't missed any pills I care about it more than anything. This month I've been spotting for about 5 days now. Usually pink or fresh looking blood. Very very little amounts but seems kinda continuous. It looks like this. Could this be a pregnancy thing? I really don't want to be, I have about 6 days until the placebo pills (5 when I take it tonight) but this has been going on about 5 days.
