Keep your pregnancy a secret?

Has anyone done this for a bit? I'm not pregnant yet but am TTC. I mainly want to keep it on the down low because I workout. And since my doctor says I'll be okay and gave me a lot of pointers how to stay safe that wont stop my fiances family (and some of mine) from telling me I shouldn't. My last pregnancy everyone was in my business and I just want this to be different this time. Im not wanting to keep it secret for forever just until I know the gender.

I know the whole "its your pregnancy dont let others tell you what to do" but I just dont want to hear it lmao.
