I have been on the pill for about a year now. My boyfriend and I usually have protected sex just to give that chance of being pregnant never happen. Though, last month, we didn't use that condom.

I tend to take the pill around the same time of the day, sometimes a couple hours later or earlier. After the incident, my period came late. Well, I can't even say it's a period. I was spotting brown throughout the whole time I should've bled. Since then, I took a test about a week later, it came back negative. So we were relieved.

But..

I missed a day on my pill after that, and we had unprotected sex again a few days after the missed pill. Though he pulled out, i'm still worried. My "period" started right on time this time.. But.. Still no blood!

Should I be worried? What could be wrong?

Please help!
