Constipation Woes

Hello fellow mummies! I’ve been experiencing severe constipation now at around week 9. I’ve tried all the natural remedies like eating more fruits, veggies, dragonfruit, prunes, prune juice etc but I think my body is too immune to them now. Just to check is there any off the shelves safe and effective products to be used for pregnant women? Thanks in advance! #pleasehelp #experiences
