Hi, yes please do raise it up to your gynae. For me, I had those episodes in trimester 2, itchiness and yellow-greenish discharge. Apparently, it’s quite common cause of hormonal changes. The doctor gave a vaginal medication to insert for 10 days and eventually the itchiness and weird coloured discharge went away. As for hygiene wise, just wash with water and always keep it dry. Make sure you don’t wear too tight of a panties, let your vagina breathe with panties that are stretchable and comfortable. Also, always keep a spare of fresh panties in your bag, just in case, in the scenario that there’s discharge on your current panties so that you can change and won’t feel uncomfortable the whole day.
