Honestly, I would say please ask your doctor first before doing anything. Since I had a history of complications, my gynac strictly advised against it in the third trimester. It is always better to be extra cautious and put the baby's safety first.
It's usually fine, but you must ask your doctor during your regular monthly follow-up. I had thyroid issues so I was always on a strict check-up routine, and I made sure to ask my doc about this too. Every pregnancy has different medical conditions, so doctor's advice is key.
Generally it is safe if you have a normal pregnancy, but please check with your gynac once to be absolutely sure. If you do, just be very gentle and avoid any pressure on your tummy. If you feel any cramps or discomfort, stop immediately and contact your doctor.
My doctor explained that unless you have conditions like placenta previa, incompetent cervix, or history of preterm labor, it is scientifically safe. The baby is well protected in the amniotic sac. But do check with your doctor to make sure your pregnancy is not classified as high-risk.
