Hi,
Welcome to HealthcareMagic Public Forum
From description, it appear that there was no penetration as first time penetration usually associated with pain. For
pregnancy also, significant amount of semen is needed.
No need to worry. Just watch for your period next time. If miss then visit nearby gynecologist.
I hope this information has been both informative and helpful for you.
Wish you Good Health.
Regards,
