Is It Possible To Get Pregnant Through Protected Sex?

So the other day me and my girlfriend kind of had inprotected sex but my penis never went in her and only rubbed on her clit and I did not cum and today I got the pill for her EC and then today we made another mistake so I put a condom on and it wouldn t fit and I was stupid enough to reverse it and try to put it on my penis but my tip of my penis did not touch the tip of the condom that of the side that I used but I didn t enter my penis into her but I did put my penis with the condom around her hole
