I am three days late for my period. i started getting cramps on the fourth day. on the fifth day i started spotting. is it possible to be pregnant?

Unlikely, but...: Can do a home pregnancy test. A urine test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or about 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon. If a woman gets her normal regular period, then she is not pregnant, and a test is not needed.
