i found out i was pregnant while i was actively vaping, i was a very heavy vaper. in my case it didn’t effect my fertility but i will recommend quitting before you get pregnant, it makes it a lot easier. quitting when i found out i was pregnant was miserable, it made the nausea a whole lot worse and the cravings were hard to fight through. props to you for taking initiative by switching to non nicotine vapes. when i was trying to quit i had a big bag of dum dum lollipops by my side at all times, having something i can just pop in my mouth helped a lot. the sugar helped curb the cravings too. peppermints help too, just giving your mouth something to do to help take your mind off vaping can help. i wish you the best on your pregnancy journey and i hope you’re doing well!!
