Ay, alam ko yan mamsh, super irritating talaga especially pag mainit at pawis! A few of us sa mom group namin nag-deal din dito and sobrang uncomfortable when you can't even wear underwear properly. Since your OB already gave you a cream, try going commando or wear loose linen pants muna habang nag-heal, at make sure na air-dry mo talaga after bathing kasi dampness makes it worse. If it's still not improving after a week or two with the cream, or parang nag-spread pa, better follow up with your OB ulit para baka kailangan ng different treatment, sometimes it could be fungal or needs a stronger approach, and you deserve to feel comfortable habang pregnant na!
