I Took a Pregnancy Test A Couple Days After I Found Out That The Condom Slipped. But When I Took The Test It Said I Was Negative. I Have Took This Test Four Times, And It's the Same Answer "Negative". But My Question Is If Im Feeling A Type Of Way About My Stomach, And The Things It Does Should I Go Get Checked Out ?

Did not take time to read any instructions huh? And did not know anything about pregnancy and having sex also ?

You can not test for several weeks, not a few days after sex. Of course it will be negative. You have to wait till you miss your next period and then wait one more week, Then you test with the first urnie of the morning.
