the struggle

I am 22 and a half stone... I have PCOS and Underactive thyroid... me and my husband have been TTC for 4 years but the weight just keeps going on... I just can't loose the weight no matter what diet I follow 😔 my husband and I have just signed up to the gym and are going to go swimming every Sunday. I don't have regular periods either so TTC has been sooo difficult. I know I need to loose weight to help get to control of my body but I just keep hitting a brick wall. I feel like it's never going to change and with that resulting in me never being able to have children... feeling very low atm 😭 but off to the gym tonyt to see how it goes
