My teen is not happy about my pregnancy

Bethany
Anyone have advise for me? My daughter is 13 and only child. She found a new in the box pregnancy test. She is soo upset and she doesn't even know yet that I already took another test and it's positive. I feel scared to tell her. I'm mad that she is being unsupportive and well like a spoiled little brat. Then part of me feels really sad that I can't share my happiness with her. After raising her alone for 13 years I got married to the most wonderful guy ever 2 months ago. We dated for almost 5 years, I know she loves him. Should we go to family counseling? I'm about 5 weeks now.
