New to the site

Hi everyone,
My name is Mikayla. I am new to the site and hope it helps me reach my goal of loosing 100lbs. I am currently pregnant with my 3rd child so for now I will be using the site to keep track of what I eat during the day but when our son is born I plan on starting a new exercise program. My current weight is 216lbs (I have been loosing weight the whole pregnancy so I can't blame being pregnant) I want to get down to 120-130. I haven't set a specific goal yet because I have been told 120 is not healthy for a person of my height, I am 5ft 9in. I am hoping I can loose around 100lbs by my son's first birthday. If anyone as tips please let me know, I am so ready to get back to being myself again!!
