First time anxiety

I had sex for the first time about a week or two ago and ever since, I've been stressing! My boyfriend has never had sex before either, but he has gotten oral, etc. from other girls. I'm on birth control but we did not use a condom. There was also a decent amount of saliva on his penis during penetration. He did not ejaculate inside of me, and I had my period a week later, but I'm still worried! I haven't had any abnormalities or symptoms of pregnancy or STDs, but of course since we didn't use protection I am still concerned that I may have contracted some sneaky std. Should I set aside money to get tested?
