just worried :(

Okay so I learned my lesson about un safe sex. 
My bf and I had sex and he is really in control of his body, he tells me when he is ready to cum
So we were at it and after a few strokes he pulls out and it did its first drip right away like pull out and drip and then the full load followed.
No cum got near my vagina.
He said he is certain he pulled out and I have nothing to worry about
Now in the middle of the night I had a lump in my throat I think it's because I was late night snacking then fell asleep
I woke up and it felt horrible 
I didn't throw up tho, I went back to sleep and by the morning it wasn't there: and now that I am thinking about it , it came back lol
I'm the type of person to worry a lot and such so it could be stress too, I have a big event coming up as well so I could be stressing about that in the back of my mind.
I just need some reassurance
It's been about 2 and a bit weeks that we've had sex 
I learned my lesson on unsafe sex, my stress is worrying me 
So I just need some reassurance 
Much appreciated 
My period is due next week If that helps
