Hair issue

Hi mummies and mummies to be, sad to say, i was born with curly base hair. I'm at 5wks+ , is it ok for me to do my usual rebonding? If not my hair is gg to be in a huge mess for the next 1yr. My last was 1yr+ ago and it's been long overude. Or what suggestions you have? #firstbaby #pregnancy #advicepls #1stimemom
