first time sex

So I had sex about two hours ago for the first time. and it was perfect but I've just been to the bathroom and my underwear is so soaked it's a clear/watery liquid it's like I've wet myself and I've had to use a pantyliner. We didn't use condoms could he of cum in me

Edited: thank you for replys I am on the pill and I did bleed but he was lovely just got carried away with the moment even so I wouldn't change anything I just embarrassed cos thought I knew everything about sex but I guess you learn as you get older
