Baby Kicking Constantly at 18w

Ar

I’m 18 weeks and the baby has been kicking all day and all night for the last few days. Is this constant activity so early normal? They feel like pretty strong kicks, too. I feel a handful of hard kicks every hour!

Also whenever I sleep on my left side, he kicks my left pelvis area squished against the bed. Then, I switch sides and the same thing happens on my other side. It’s the strangest thing. Could this mean he’s uncomfortable in there?
