I've been in the pill for a few months now and everything has been well. Some weeks ago I had unprotected Intercourse but I doubt my partner ejaculated or had any pre-***. I was due to come on my cycle about a week later and I did. I did not notice any change that differed from previous cycles. I'm now two weeks into a new pack and today I noticed brown discharge and later I saw some blood. This isn't normal for me. I normally take my pill the same time everyday, but some days I was an hour or so late taking them. However I have not missed any pills nor experienced abdominal pains. I this something I should expect?
