Approx. 4+3 and Can't Get Comfortable?

Ok, FTM (to be) here.. I have my first OB appointment tomorrow, but medically speaking, based on my last period, I am approximately 4 weeks and 3 days. Since last night, I am having such a horrible time trying to get comfortable in bed. No matter what I do, or how tired I am, I cannot get comfortable.. is this normal, I mean, being this early on? **Still posting anon. because no one knows yet besides my husband, and I'm not sure if anyone I know is on this app. *****Edit (reply to comments) :: By uncomfortable, I mean, like, restless. Like I can't find a position to lay in that feels good enough to fall asleep. BUT, that only lasts for about 30 minutes and then I'm fine. And no pain really; just having light period-like cramps.
