I ve had protected sex less than two weeks ago. i was supposed to have my period yesterday but i didnt and woke up today with spotting. is it possible that im pregnant? what should i do?

Hard to guess: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A home urine pregnancy test gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), 1 week after missing a period, or after having a "weird" period.
