OB nurse being "rude" already...

We're expecting baby #2 and our son is currently 6 months. We wanted our kids close in age and with my endometriosis and having to take fertility treatments to conceive our son we wanted to try again early. First cycle trying and we got our bfp and due in October ❤. When I called my OB's office his head nurse responded to my voicemail and the first thing she said was "what's going on with you?" which isn't rude per say but it's not what you want to hear. Then after my blood work came back positive she asked "have you even started pre-natals? Do you have any clue what your cycles even were?" I explained to her that this was not a accident and she said "alright then, I guess let's get you a appointment set up." I understand any doctor will tell you that the suggested time to consider another baby is 12 months but I'm already getting comments from friends/family about and now it's on my doctors end too, and my OB knows our plans/history. Sorry for the bitching just annoyed...
