If you put it in my girlfriend without a condom for maybe 20 seconds max and never came now she is like 2 to 3 weeks late and every test comes back negative what are the chances she could be pregnant?
Well, first of all you should not have sex without a condom one
for this reason of getting your girlfriend pregnant and two you may
get or give STD's to each other. But what's done is done and yes it
is possible to get her pregnant because there is such a thing as
pre-cum. Therefore, I would have her get tested at a doctor to make
sure of the reason why she is late. Then be sure to always use a
condom so you will not have to worry about this kind of thing
anymore. It can be very stressful to worry so it's better to just
know. Good luck!
