If she had sex two weeks or more ago, she'll be able to take a pregnancy test and the HCG hormone will show up on the test. You can take a pregnancy test 14 days after unprotected sex to see if your pregnant. I suggest buying a package of them (some come with 2, others with 3) just to be safe. Buying in bulk is ultimately cheaper. So, if what your saying is true about her having sex a few weeks ago, she can take a pregnancy test and it will come out accurately. But, like I said, buy a couple and take them one day at a time to see if the results change, because it can happen. She could take a home pregnancy test that comes up negative and then take another that comes up positive. Tell her it's safe to go ahead and take a home pregnancy test NOW instead of waiting and stressing about it.
