I had my period on Descember 28,I had unprotected sex on the 8,9,10.. a lots time before 22 of January.. on 22 of January I had been spotting but it was dark brown.. now it's February 1st. I still haven't see my period,I took some pregnancy test they came up negative.. it's there a chance I can be pregnant...

Any time you have sex, protected or unprotected, you can get pregnant - so the answer is, yes, you could be pregnant.

Thkz Judy :)... it's been 4 days now since I don't see my period.. so y the test keep saying negative.. I'm worry all I feel is sleepy, nauseous,and some short pain on my lower belly that's set..

Think it might be time to visit the doctors to confirm.
