Hi Doctors. I am 20, Male. I just had sex with my girlfriend yesterday, March 30, around 6pm. After withdrawal, I dried my penis using facial tissue then after a few minutes, have sex again. After around midnight, we start having sex again but I just dry my penis which has drops of semen using tissue and insert it immediately after i ejaculated by withdrawal. Is there a large chance of getting my girlfriend pregnant? I am worried about pre-cum. By the way, around 8:10 am, I had her took 4 pills of Nordette (as there is no Plan B in the Philippines) and waiting her to take the second dose later. Her last menstrual period happened March 11. Thank you very much. I ll much appreciate your help.
