Baby movements at 26 weeks

I'm 26 weeks tomorrow and I haven't felt my baby move in 2 and a half days.
He's normally super super active and I can feel him all the time but I had a few uncomfortable pains on Wednesday evening whilst he was kicking then on Thursday I felt him once or twice then yesterday I felt him once and so far today I've felt nothing.
I've been googling other people's stories and they said that baby could be at the back of my uterus but I'm just so worried.
Should I go into my midwife just to be sure? 
Went to the hospital and they checked babies heartbeat. Was at 135 and everything was okay with him thank goodness! I can now look forward to my holiday this week without worrying about my baby! Thanks all for your comments and support!👶🏼😘
