Girls, Can insomnia and really bad anxiety at nightime be early pregan any symptoms?

I've noticed that this week everytime I try and go to sleep I'm really tired but can't sleep, and I have really bad anxiety at night time now? I had sex 3 weeks ago unprotected when I was ovulating (I'm 20 btw) and is it possible to not have any other symptoms than just those two?
I'm still waiting for my period to come, and my calender says it's supposed to start tomorrow.. well technically today, it's 2 am in the morning right now. And I'm not showing any period signs when I usually do. I'm waiting to take a pregnany test until I actually miss a couple days of when my period is supposed to start.

Pregnancy** stupid phone. And I'm also dizzy at night time a lot when I lay down, like I just feel weird and light headed.
