I have my boyfriend a hand job and when he finished he finished into his shorts just to be careful. My hands got some of the sperm on it through his shorts and I immediately went and washed it off with soap and water. This was on Sunday and I had started my period on Thursday so was still on period with a pad on. Later that night I changed my pad and touched down there. Is there anyway I could be pregnant? I am a day late for my period but have been so stressed and convinced that I am that maybe I've caused stressed. I took a test and it was negative . Thanks
