 [ Symptoms ] i had sex almost two months ago would i know if i was pregnant by now  i took four home test and yesterday my obgyn did a dip test as well and they all came back negative she even did a pelvic exam so i should be okay right [ Disease ] a home remedy is perfectly appropriate for what you are describing a few suggestions humidify the air either with a commercial humidifier or by warming not boiling an open pan of water on the stove be sure to monitor the pan so it does not run dry and start a fire pour hot not boiling water in a pan then drape a towel over your head to create a tent and spend a few minutes breathing the humidified air you can safely use small amounts of water based lubricant like plain k y jelly in your nasal passages to keep them moist this is especially effective when done at bedtime simply place a small dab of the lubricant just inside each nostril you also can make your own saline nasal solution by combining 1 cup 8 ounces of distilled water with 12 teaspoon of salt heat and stir this mixture until well combined allow to cool use a dropper to instill one or two drops into each nostril keep this mixture refrigerated and discard after a week hope this helps
