My last period came on the 19th february i had light bleeding on the day my period suppose to come for 2 days then it stop. can i be pregnant?

Possible pregnancy: Can do a pregnancy test. A urine pregnancy test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 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, and thus lead to a repeat test. If a woman gets her NORMAL regular period, then she is not pregnant.
