Vaginal discharge

Hi mums! I am now 20weeks pregnant and from the beginning of the pregnancy I’ve been having a vaginal discharge, I tried to treat it but it disappeared for a while and then it comes back again, I find it annoying since it was greenish in color ( but not itchy and non smelly) I tried to consult with my obgyn and he said that it is normal and offered me a vaginal douche in hospital if it’s really bothering me. Anyone with same problem here? How you handle it since I stopped ML with my husband cause by this, thx in advance!
