Hello everyone, my little one has become less active, sometimes I only feel like he's wriggling, the jolts are very rare. According to ultrasound everything seems normal. But the doctor asked if I had been sick the day before and whether I felt any movements. I haven't been sick, it's strange how that is. I heard that boys are more lethargic and move less. Maybe I'm panicking for nothing, of course.
