All mummy, must sure your gynae fee include scrub test in the 37 weeks. Understand what is GBS as this is very important especially if you intend to have a nature delivery. Pls google GBS to understand what is this. It is very common of 20% mummy might carry GBS bacterial and it's possible to pass to the baby.
But this test will only conduct in the 37 weeks and thus gynae dont't tell you . To ensure mummy free from GBS, personal hygiene is very important especially after you wee wee. Do invest a bidet in your wash room so that you can ensure more hygiene . Japan and Korean mummy have low % of GBS as they have bidet in every home and this is hardly see in Singapore .
There is few kind of bidet available locally, make sure you get those which provide for female or double nozzle type.
