Hi. I am currently on a combination birth control and have been for quite awhile. I'm not very consistent timing wise but I do take it every day. About two weeks ago my boyfriend and I were hanging out. I gave him a hand job and Im not really sure if anything got on my hand but I'm worried I maybe had something under my nails. After I got home I wasn't thinking and started playing with myself. Since then I have been extremely worried that I could be pregnant. I know this may seem dumb but I need to put my mind at ease. What is the likelihood I could be pregnant?
