Anybody else had weird feelings?

I haven't called my obgyn because the office is closed but last night I had random pain (very mild) in my left side a few inches down on my belly button, almost felt like something kept poking me or like there was a rod in my tummy. I've heard of round ligament pain so I thought maybe this was it but it's kinda scaring me. It wasn't consistent and it completely goes away if I lay down on my tummy/side  in a comfortable position. Anybody else experience this? I'm 15 weeks today.
