December 11th my boyfriend rubbed his penis on my vagina briefly and afterwards there was pre seminal fluid on my vagina. There was never any penetration. I am on birth control and have been for two years however I was a two days behind at that point but since Ive been taking them correctly. I had my period for December. However I havent had my period for January and so far I am three days late. I have taken two pregnancy tests in the past two days and both have come up negative. So am I pregnant?
