Okay so I had sex about 3 weeks ago and my period is 2 days late. I looked up symptoms on google but I don’t 100% trust google. I haven’t been throwing up but for the past weeks I’ve been having nausea and things of that sort. I didn’t use a condom, I should’ve and we tried but things happen, and he didn’t cum inside of me but I read that pre cum could possibly lead to pregnancy. Please help! How can I find out or symptoms to focus on before taking a test?
