am I pregnat?

Alyssa
Ok I'm kinda new to this app but. I need your guys help. I had sex with my boyfriend without a condom. He didn't cum in me and he dick was in me for like fifteen seconds my periods on three days. I'm super terrified I'm pregnat. And my boobs have been kinda sore lately and I have been super stressed with life but iem freaking out. I haven't needed to pee a lot. But since I'm stressed I haven't been eating much and my body has felt kinda out of it lately. It's hard to explain like I'm fine but just a little tired. I need advice.
