Ok, so I'm freaking out massively! I have a phobia of vomiting (emetophobia) and I'm 5wks pregnant.
Although I'm over the moon to be pregnant, I'm absolutely terrified about the thought of feeling nauseous/vomiting during pregnancy. It's all I've been thinking about since I found out I'm pregnant πŸ˜” I know it sounds really stupid but unfortunately with this phobia it makes you completely irrational.Β 
So... How many of you suffered with morning sickness and to what degree? Ie nausea but no vomiting, vomiting once a day, nothing at all etc and when did it start?Β 
Thanks in advance!Β
