It's because she claims she has passed out due to pregnancy whilst wearing a mask, that makes her exempt. Earlier in my pregnancy I often felt like that too and did take mine off at a scan - but it was at the point where I knew I couldn't last any longer wearing it, rather than just not bothering at all. It was actually my husband that took it off me and reacted with such urgency I felt like there was something seriously wrong with me, but he could see I was going to go. If it's a true case of wear a mask and pass out or not wear one they would rather you didn't wear one (that's what I was told), but she has certainly never seemed like she is going to or has recently passed out despite often vlogging on these trips. I also seem to think that when they have filmed at her scans/appointments she has had a mask on - because she knows they would know she isn't in any danger of passing out and wouldn't want to mention it to a doctor because it's not actually true.Longtime lurker.
Being pregnant on its own does not excempt you from wearing a mask - I recently had a baby and was a higher risk pregnancy and had lots of hospital appointments and had to wear a mask to them all.
Also her cold sores are herpes they are caused by the type 1 strain and probably worse due to her pregnancy, she could easily get oral medication from her GP to try and prevent them given how often she has them if she just called the she wouldn’t even need seen face to face
If she genuinely felt like she might pass out, she wouldn't be shopping in primark, or driving all the way to get Nana to take her to the White Rose centre. She doesn't need a coat on - she presumably went straight from the car into a shopping centre. Most people wouldn't bother with a big coat for that, never mind if they are scared of getting too hot and passing out whilst pregnant, with their child and Nana.
I don't believe she's ever passed out or even come close this pregnancy, she just wants to make it seem a lot more dramatic than it really is - same with the bleeds she has.
