Feeling worried and anxious 😞

I'm 17 weeks and still haven't been able to feel my baby. Last time i heard the heart was almost two weeks ago. Many of my pregnancy symptoms have basically gone away besides the occasional nausea and swollen breasts. I haven't really began showing so that's another thing I'm worried about. I'm high risk with type one diabetes so I'm very worried. I don't have another appt until early Feb. Any advice would be helpful. I'm also trying to buy a doppler to put my nerves at ease but haven't found any stores that carry them & waiting to get one online is too long for me. I'm in San Jose CA. Please help this FTM ladies 💗😒
