Hi Nattie my name is celina. i am 35 and have just recently married. My husband and i have decided that we want children. i have been very bad on my diet for nearly 15 yrs. i thought to go back on my diet would be so difficult as the last i remember i was on 7 exchanges. I have found it easier than i thought once i put my mind to it. i am now on 10 exchanges and my phe is very low if i was not trying to have a child i think i would be on at least 20 exchanges. i find this amazing. i read somewhere that it seems to be easier for someone who was off the diet to go back on to try for a baby. Do you find this? I see it has been a while since you have posted this. I would love to know how you got on.
