Constipation during pregnancy

I have constipation issues prior to pregnancy and it got worse during pregnancy. Science shows that our digestion works slowly during pregnancy to allow our body to fully absorb the nutrients from our food. Before I was taking detox tea and a special plum to help me. But now my gynae says no more tea. So just the plum. It helps but some days I still feel very tight and bloated. I'm eating more fruits and drinking lots of water. Still not regular but every other day is good enough
