Early pregnancy symptoms

Me and my bf have only had sex twice, each time we used a condom and he pulled out and I'm on birth control. The last time we did have sex was Feb 4th and I got my period, like 2 days early I'm pretty sure (started on Feb 8th). But what're some early pregnancy symptoms bc I'm kinda paranoid (thanks to my anxiety) even though we've take so many precautions. I'm just curious. Thanks in advance.
