Hi. I'm 23 weeks pregnant and I decided to go vegetarian (for the beginning and then transit to a vegan lifestyle)
Is there any stuff I need to know? Things I need to buy/try? Tricks I can do not to be tempted to eat any meat ? How did you start your transition?
Thanks for the help and all the advices are welcome 🤰🏼💕☺️
