other twin not kicking as much like before

mummies, im nearing my 2nd trimester and i noticed that my other twin is not kicking as much as the other twin. yung position po nila is left and and right naman pero one part lang nararamdaman ko. okay lang po ba to or need ko na magpa check up? ##1stimemom #advicepls #firstbaby #pleasehelp #pregnancy
