Ive been using the pregnacare pre conception vitamins. Having done some research, the Internet seems to suggest taking a higher dose of 5mg if you are overweight. That's definitely me 
As GPs and midwives don't see you until around week 10, this is after the critical neuro development. However, I'm kinda worried to just start taking a higher dose somehow. Is it safe to just take 5mg anyway? Has anyone done this?
Thank you!
