Yes I'm using the baby centre app, it's good! They also have another version for when your baby is born. I'm using that also for my toddler. Quite accurate the way they describe the child's behaviour at certain age.
I did nail gelish before during pregnancy. Once only. It's ok however when you go nail salon, you will be breathing in the nail polish fumes...which in the long run is not advisable.
Some mummies I know went to do hair rebonding before delivery. Xiaxue the blogger also went to colour her hair. However, when I asked my gynae for permission to perm my hair...perming won't touch my scalp...she said no. She prefers me to play safe by waiting after delivery, after breastfeeding too. So last pregnancy, I had half black, half brown hair. Ugly! And this pregnancy, I will have messy hair. Ugly too!
Btw mummies, you can all still go facials, just don't do anything with machines. Plain massage type of facials only. Can't do IPL also.
