Periods two weeks delayed. Took i-pill.

I had sex on April 1 (it was my first time) and my partner used a condom and later I had an i-pill after an hour just to be sure.

My periods came on Feb 28 and March 28 before that. So they were due on April 28 but its been two weeks past that date and they have still not come.

I have taken three HCG pregnancy tests(mankind's preganews) after the due date (in a week's span)and all three have turned out to be negative.

I am having normal symptoms that show up before periods since two weeks but still no periods.

I am waiting because I found numerous number of girls having this delay but its mentioned in ipill's faq that after 7 days to consult a doc. Going to a doc is not possible.

What should I do? :( I have my semesters coming up in a week's time and I can't concentrate. I'm freaking out.

Are abortion pills an option? Please help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
