Hi im 18 and i have not had sexual intercourse , i abstain from that but about five weeks ago i was fingered and im afraid there might have been some precum on his had and if there was it was minimal and some time had passed since he came in contact with it, the month ended and my period was late, i waited a week after it was due to take a pregnancy test and it came out negative but still no period then a week and half later i took another one and it still came out negative well now its three and half weeks late and still no period and im a very regular person i have never missed a period nor have i ever been this late. so could i still be pregnant? and if not what could be a possibility for my super late period?
