Lmp april 22, last 4 days, 30 day cycle. had unprotected sex may 1, pull out method. what are the chances of me being pregnant?

Low chances: The whole point of pulling a penis out of a vagina is to avoid getting sperm into the vagina. Without sperm, there can be no pregnancy. So, getting pregnant in this case requires a failure of the pull-out method... which does happen (and women do get pregnant sometimes). If the next normal regular period doesn't come, one can do a home pregnancy test when that period is late by a week.
