Feeling as I am going to faint

Kiki 🍉

In the past week I keep feeling like I am going to faint if I don't eat straight away. I am 6 weeks pregnant and today I was so dizzy and felt like I was about to faint so I went to seek help from a pharmacy and I vomited three times and felt unwell for the rest of the day.

Does anyone else feel as though they are going to faint if they don't eat straight away?
