So i had unprotected sex 6 weeks ago my period was late and i took a pregnancy test it came back negative and then i got it my period but only for 2 days can i be pregnant ?

Hard to guess: Many women have occasional variation of their mucus discharge, some spotting between periods, a heavier or lighter period, a longer or shorter period, or even a missed period. Having one or two of these symptoms doesn’t necessarily mean there is a medical problem, but a visit to one’s primary care or Ob-Gyn doctor is a good idea if symptoms are recurring. Home pregnancy tests are very accurate.
