Quite simply if sperm got into your vagina then yes you could be pregnant.
If no sperm got into your vagina then no you can not be pregnant.
However, we were not there when it happened, we do not posess psychic powers.
I'm sorry haliparrot but we simply
do not know if you are pregnant.
If you really really want to know wait until your period is over due and then test.
Yes some tests can pick up before your period is due (first response) but why waste the money, just see if your period comes along or not first.
