I flew from London to Beijing
on the 1st of November and arrived
the next day, missing my
pill. I then took two. Coming back
on the 10th, I arrived home on the same day and continued taking the pill normally. On the 15 and 16th, I had sex with my boyfriend. On the 20th, I was a couple of hours late in taking my pill. Today is supposed to be period day, but it hasn't shown up, despite the fact that it's usually like clockwork.
