2 Weeks after Sex

Ren

Hi Team! Just want to know if someone noticed getting pregnant or pregnancy symptoms as early as 2 weeks after sex. My partner and I badly wanted to have a baby but he only spent 2 weeks with me as we're on LDR. We had sex days before my period and 2 days after my period. It's been 2 weeks since we our first (before my period). I'm confused with the symptoms but I'm having a PMS which I usually not experiencing before. Any ideas , knowledge is appreciated, thanks in advance!
