I’m experiencing it too at 29 weeks and now I’m 30 weeks. My mum told me it’s normal because your baby is growing inside the tummy but it hurts. I work in a preschool setting and I’m taking care of 24 months old children where I need to be seated on the floor..I even ask my husband and mum to massage but it doesn’t go away. Hopefully during and after delivery it will go away 😥
