Trouble sleeping :(


Based off various websites etc. I'm about 7 weeks pregnant. It's nearly 4am here in England and I just can't sleep at all. I am wide awake but so tired. I don't know what to do, does anyone have any advice? If I can't get sleep, will my baby be okay? I did have a 2 hour nap about 12 hours ago, is that maybe the reason I can't sleep now?

Any answers would be greatly appreciated, and thank you in advance.
