Wow - sounds like you are doing absolutely everything you can!!! Hang in there - you are a great mum and looking after that bub of yours wonderfully by the sound of it. It is hard work and all the worry about food and the weight of the baby can go your head in - so I can relate to the worrying. As others have suggested it may be worth giving your DE/Endo a call and checking in with them - to reassure yourself you are on track.

Take care and be kind to yourself!
