10 days after sex.

Hey guys! So it's been 10 days since the first day I had sex but I had sex all week the week that I was fertile.. my breasts are soooo tender and I just want juice because my stomach has been feeling nauseous. Is it to early to have these signs? Am I just crazy thinking I'm pregnant haha or has anyone had this happen and them be pregnant 😊😊 thank you!  Also there was 0 protection and he did cum in me sorry for tmi but if that helps lol Please any info helps!!
