Sino po dto may allergy sinusitis/rhinitis? Ano po recommend ng OB po sainyo?

ako, prior my pregnancy after ng covid infection ko, natrigger yung allergic rhinitis. then nung magbuntis ako mas lumala esp nung 1st tri. my OB adviced na magpalit ng linens, curtains, pillows lahat...maglinis ng bahay always talaga., invest ng air purifier, drink lots of water and vit C supplement plus fruits/veggies. at salinase spray lang. better ask ypur OB na lang po.
