Question

Can anyone help answer this question? Please... Kinda freaking out.
I was hanging out with my boyfriend on Monday, we were in his hottube.. Anyway.. He stuck his dick in me all the way without a condom, while we were in the water.. He was only in for less then a minute.. But is there anyway I could have got pregnant from it? He never came in me.. We got out and put a condom on before continuing. 
Please help... 😢
