Young and anxious

Kayla • Learning to love the life I was gifted
I'm 16 years old and my current boyfriend is my first sexual partner ever. We always use protection and I'm on the pill and he always pulls out as well. 
Last time we had sex was almost a month ago and I finished him before we had intercourse and he hadn't ejaculated except for precum; he wiped is penis off and put the condom on then wiped the condom off and we had ontercourse. 
I wasn't on the pill yet but started it a week later. Being young and VERY new to this I'm having very anxious thought. PLEASE HELP
