Unusual: BFN & No Period?

First off I'm 24, have one step child I raise as my own, and my husband and I have a child together as well. Both were not planned in either of our lives lol (his son was a surprise with his ex). We've been together for over 3 years total. We are TTC together now and planning is very exciting! Yet, I'm over a full week past my period's day of when it was supposed to start.... All HPT's show a big fat negative (taken 7 total since "missing it"!). Pretty heartbreaking.... Is it possibly just my body showing me I'm too anxious? Or should I go ahead and call my OB/GYN's office for advice since I'm beyond confused? I just don't want them to "judge me" just because I'm so anxious for our last addition to our family and I'm open to all advise, as I have no clue what's going on & didn't know if anyone else has ever been through this???
Please lay off any negativity. If you can't say something nice, don't say anything at all! :) Thanks!!
