I had unprotected sex 2 weeks before my period was due which was February 28, it never came and it's been 1 week since then. I took a pregnancy test the day after it was due and came back negative but I had unprotected sex again March 3. Is there a chance I could be pregnant?

There's a very good chance of pregnancy. The test you took was taken too early to be accurate. Since you're now a week late I'd try another test. Make sure to use first morning urine, and follow the directions exactly. If that test is negative I'd wait another week and test again. If that test is also negative than wait for your next period. If you miss it then it's time to get a blood test done.

Good luck.

It sounds like a very good chance. The timing was idea for it to happen.

Normally home tests need to wait till you are about two week late, so wait about one week, and test again, Make sure it is first thing in the morning as soon as you wake up. Follow instructions carefully.

In other words, exactly what Alty said. :)
