hi girls, ive just fount out im pregnant again after a miscarriage in February. I am a rather big girl, not sure my weight but im in roughly in a size 18 top(uk) and i was wondering if anyone can help with what i can and cant eat and what exercise i can do to keep myself going. i do have asthma so i do get out of breath easy. i just dont want to go through another miscarriage again

im sorry if this is in the wrong group also
