Oo, totally normal yan during pregnancy! A few of us mums experienced it around that stage, parang may amoy na hindi talaga nandoon, super weird right? It's usually from hormonal changes na nag-aaffect sa sense of smell mo, kaya mas sensitive ka or nakakahanap ng odd scents. That said, best to mention it sa OB mo next visit para ma-rule out anything else, pero most of the time it's just one of those crazy pregnancy things na dadaan lang!
