I've been on the pill for several months now, but had a break of about a week in mid-January where I had unprotected sex with my boyfriend. I then went back on the pill, but since then have been feeling sick and tired. I now just finished my second course of pills and came on my period, but the bleeding is very very light. I took a pregnancy test which showed up negative. I read on-line that home pregnancy tests aren't always reliable.... especially cheap ones. Is it possible that I'm pregnant? I am going to the doctor's about it, but the appointment is over a week away and not knowing is driving me slightly insane.
