I went to my weekly appointment today the doctor told me he wants to induce me do to how swollen my legs arm and face are. So he told me that I had to be in the hospital tomorrow at 8:00pm am so nervous because am so far along and I haven't dilated I haven't lost my mucus plug. I feel like I've been pregnant for ever.
