Assalamualaikum mama! Cyst masa hamil memang biasa terjadi, tapi sebaiknya beritahu doctor pasal ni supaya dia monitor dengan proper, ada je a few mum friends I know yang ada cyst during pregnancy dan doctor dorang just keep track through ultrasound, takda masalah pun. Untuk makanan, takda specific restriction sih, tapi generally eat healthy (lots of fruits, veggies, protein) and stay hydrated, avoid extreme heat, dan jangan stress sangat sebab that affects hormones. Make sure you follow up with your OB regularly so they can advise based on the size and location of your cyst, sometimes they monitor je, sometimes kena action. Mana tahu it resolves on its own postpartum
