Broody, I've had a few recent wobbles too. if I start to have a panic moment of not feeling movements for while then I lie down and press into my bump (just hard / deep enough so baby can feel it) to try and make him respond and wait to see if get a poke back. Can take a few good old prods from me (probably waking him up!) but always got one back. Which helped reassure me.
Or try the lie down, v cold water / drink and wait to see. Then keep v close eye of what you feel over generally next few hours and trust your instincts. If you don't feel right about it go get checked.
Did those faint kicks an hr ago turn into more?
it's never silly to worry but defo monitor. I also found a little note book and started actually writing down the times I felt things (did this Tues and Weds as he seems v quiet over bank hol) just a v simple list of times. He then decided to move like every hour those days! but found it v reassuring to see it written down in black and white when I last felt something and how many times in the day. Our preggo brains probably forget actually and go into panic stations far too easily... Might be good way to reassure you over next few days. I only did it those two days but will do again if I feel the need to keep eye on it again...
