Could I be pregnant?! (1st pregnancy scare)

Melanie
I'm 20 years old, and had just lost my virginity to my boyfriend. We had used the pullout method cause it just happened in the heat of the moment and didn't have anything prepared. He didn't cum inside me, but I've heard risks about pre-cum? I haven't had any symptoms, but there's still the fear of getting pregnant. My cycle length is 27 days on average. I had sex on my 10th day and am currently on my 17th day. I didn't  take any emergency contraception and not sure when I would take a pregnancy test to get the most accurate results. 
This was my first time having sex and so I just want to know if I indeed could be pregnant or if I can finally take a small breather. And yes, I've learned my lesson from this. I will use condoms the next time(s), at any and every cost. 
Any advice would greatly appreciated!
