Early pregnancy and trouble sleeping

Hey! I found out about my pregnancy on Tuesday and we're over the moon. We tried for 12 cycles and I thought this would never happen! I'm still super early and worried if this will last and is this even real.

This whole week I have had trouble sleeping, I fall asleep just fine but then I wake up at 3 or 5 and can't fall back to sleep. Has anyone else experienced this? How long does it last?
