Baby not do active

I experienced the same thing when im on 26 wks. Baby was moving hard at all for almost a day & half. But when I went for a check, I found out that my place ta is at the back hence, I couldn’t feel much kick. Baby head is also at the top as his back (spine) was facing outwards. Not too worry, cos next few days, I can feel my baby kick again.. more active this time.
