Anxious to announce?

Is anyone else feeling anxious to announce? I'm afraid I'm not going to get support from my family, mostly my mom. She is a very outspoken person and I don't think she's going to take this news well. This will be our 4th baby, I have a 8, 3, and 1 year old. Our youngest was unplanned and so is this baby. We struggled with infertility with my first 2. I guess my body has figured out what to do now. Lol My husband is very supportive and he told me that we just aren't going to tolerate anyone being negative. I am a nurse and my husband is also a healthcare worker. We have decent jobs and provide a modest but loving home for our children. I hate that I feel this way. I'm hoping that its just hormones making me anxious. This baby may be unplanned, but so wanted.
