Venting.. and scared

So I’m eighteen yrs old and in my first year of college. I’ve been dating my boyfriend for a little over a year now. We had sex on the 17th of December (around 4-5 says before ovulation.) We used a condom but he didn’t pull out all of the way. Afterwards we even checked for leaking and etc, but there was none. I’ve been experiencing symptoms for the past eight days but I have really bad anxiety with this scare. My period is expected tomorrow, but I’m pretty convinced I’m pregnant but I know I could just be freaking out. I’m so scared and don’t know what to do. I haven’t been able to sleep at night... like at all.. for the past like four nights. I took a test this past Friday, but I know it’s more than likely too soon to get an accurate test. I’m just so scared.
