Hi Libby,
Any pharmacy should be able to do your check ups. If you have a large Asda store near you with a pharmacy, they are very good. I know a few people who have theirs done there, including me.
Good luck in finding somewhere.
Gingette, my LLC has let someone start and bring the form in at their first weigh in. Obviously, if they didn't have it she wouldn't be able to give them the packs. As long as it is done, you will be fine.
Good luck for all of your journeys you May starters. You will be where I am in no time.
