Ay totoo yan, especially when pregnant kasi mas oily ang skin at mas active ang sweat glands natin! One of my mum friends swears by using antiperspirant deodorant instead of regular deo, she said it really helped lessen the smell throughout the day, at you can reapply if needed. Mas mabilis lang talaga mabango during pregnancy, so I'd say try a stronger formula or switch brands to find what works for your body, kasi bawat mama is different. Good luck, mama!
