I have been on Lo Ovral for a few years now, and every once in a while I take my pills back to back so I dont have my period (yes, I know you shouldnt do it all the time) So, I was supposed to take my placebo pills last week and went straight to the next pack. I had sex and had some break through bleeding and I figured it was normal b/c that was the week I am supposed to get my period anyways. Now this week is technically my 2nd week of pills and today when I wipe I noticed blood on the toilet paper as if i had a light period going on, but not enough to need a tampon. I havent came across this before....why is this happening?

Also, why do we sometimes break through bleed during sex...It is so annoying when this happens.

thanks!
