Please Clear the Doubts so much anxiety.

Hello Sir/madam My concern is that me and my 20 yr gf did an outcourse on 25th December no penetration was there and she is still virging intact hymen and we still used protection for rubbing our genitals just for that experience so concern is ejaculation happened everything was safe I had checked but her periods are not there and her last period was on 27th nov what should we do..? Today is 29th I talked to a Sr.Doctor of BL kapoor Hospital Delhi he said not to worry no penetration plus protection plus 2 days before periods No way of concieveing is it right? Do we stay calm and wait for periods to happen? What is the possibility coz if it took another level she can't get out of her house we will be died! Please is this correct! Help me nd guide me the best.. Hoping for the good Thank you!
