How safe is it?

Hi everyone! My partner and i are both really excited that have started taking the pill because... well we both really like the idea of him ejaculating in me. Its been almost 2 weeks since my start date and the latest I’ve been with taking my pill is maybe 10 minutes. From your experience how safe is it to do this???

And please im not here for “if you dont want a baby dont have sex comments” please and thank you.
