No movement

I'm 25w +6. I haven't felt bub move in the last 4hrs at all. I had sex with my fiancé which usually gets her moving around afterwards but she didn't move. I had really painful braxton hicks for about 20mins which then settled down to just bad period like pains and then started to just focus on her movements. I've been focusing for almost an hr and haven't felt anything. Should I call now or wait until morning? It's 1.15am.
