My friend dry humped her boyfriend in Feb.she was wearing only a thin panty and he his boxers.he did not ejaculate but both their underwears were wet.around 15 days after that she got her period.this was around 27th Feb.and after that she took a home pregnancy test on 5th,11th and 17th or March all showing negative.her period in march was due around 3 days ago and it hasn't appeared yet.does she need to take a pregnancy test again?are the tests taken by her already accurate? Was it too early to test?
Thank you in advance.she is really worried about this
