YES, if you watch her videos she has only mentioned it like a million times in every video since she and Byron announced it.
On July 19th Rachel and Byron made a video on Rachel YouTube channel CheckInTheMirror confirming that she was 14 weeks pregnant.
There were some rumors before floating around YouTube and she just felt like she couldn't hide it any longer. I really don't get it because now when she is 6 months pregnant you can barely see her baby bump, it's so tiny!
They are expecting a boy early next year.
