Im Scared

 OK, I lost my virginity on January 22 (5 days ago). He used a condom and I Believe there were no breaks in the condom. However, after he took my virginity and the next day came, my stomach started to feel very weird I started getting lower back pains, a semi tender boob, and I’ve had diarrhea mixed with mild cramping of my lower stomach. I’ve googled pregnancy symptoms and I think I have only two of them but I am really scared of the possibility that I could be pregnant. Im 17 btw. My period is scheduled for 9 days from now but first response says i can take a test on thursday. I think stressing myself out about potentially being pregnant and over searching everything online is causing me to stress myself out. My calendar says the day i had sex, theres a 22% chance of pregnancy and now it says (after logging i had sex) that there’s a 3% chance of pregnancy, which is kind of reassuring.

I just think im over analyzing it, especially since it was my first time...i just can’t stop crying and im honestly really scared. Please send reassuring words or advice.
