Not sure

Wasn’t exactly sure where to post but hubby and I were fooling around (8 weeks post partum- mirena taking foooorever to be ordered by dr office) so he gets carried away and he had inserted himself about 3 times and when I realized what was happening and yelled at him it stopped. So no orgasm from him by means of intercourse. Not sure if I was ovulating but I was definitely cramping the day before, another app timed that as my fertile window. Scared to death I bought and took a plan b within 2 hours. I am now terrified I’m the 1% or whatever percent to get pregnant after something that seems kinda small. What do you think?
