Should I be worried??

I was feeling the boys moving much more a couple weeks ago, I’m 17 weeks and 2 days now and for the past 2-3 days I’ve had a horrible throbbing headache and no energy. In fact after waking today I was back asleep in less than 2 hours later and slept 3 extra hours! My stomach is bigger, but I’ve not felt any movement in a while and with them being identical twins, I’ve become a bit worried.. is it normal in twins to move less due to lack of space? Or should I go to the hospital and get checked out? 😰😰😰
