I'm having my second pregnancy, it's currently week 19. I don't feel any kicks anymore. In my first pregnancy at this stage there were clear kicks. Now, ideally, I should be feeling them, but there are no pinches at all. Not even hints. No fish or frogs, and all that. In general, I don't feel pregnant. Only nausea from morning only calms me down ?
