chances of pregnancy with pre cum are very less. for pregnancy to occur two things are important: 1) firstly pregnancy occurs during the time of ovulation when a mature egg is released from the follicle. it usually occurs regularly around day 14 of a 28-day menstrual cycle. 2) secondly for pregnancy to occur the sperms need to be ejaculated inside the vagina or there should be entry of sperms inside the vagina which travel through the cervix and uterus to reach the egg in the fallopian tube. from what you have described chances of pregnancy are less. it is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. for exact diagnosis you are requested to consult your doctor. i sincerely hope that helps. take care and regards.
