last period was 9th feb and lasted till 14th feb. I had foreplay on the 14th, there was some **** at the top of my panst where it had dripped on me, i took these off and went for a shower, i had washed my body and hands completely and then touched my clit. I was worried so took the ellaone pill at 118 hours. My periods due tomorrow and i feel no symptoms. I took a pregnancy test on the 28th and it was negative. What are the chances??
