Am I pregnant

So me and my ex had sex probably about 2 weeks/week and a half ago and he used a condom and didn’t cum in me(gave him head before where he came then he put on the condom and proceeded) but i was ovulating and I’m not on birth control but he didn’t finish in me. I’m probably just paranoid but could I be pregnant? I’ve been feeling more bloated lately and have had migraines but idk if that’s related to anything. I just need reassurance that I’m most likely not pregnant😭 help

Update now I have cramps and diarrhea😢
