I think I may have concieved!

Ok. I think I may have concieved but it's wayyy to early to tell because I haven't had my missed period yet. But a week ago, I noticed my cm egg white and then watery so my and partner had sex. This week, I been urinating a lot more than usual and a bit nauseous. Not throwing up but feeling like I have to. My period is a week and a half away but is it too early to tell? Have you guys noticed that u was were before you took a test? What were your symptoms? Is it possible to know before you even had your missed period??
