Nervous, am I really pregnant

Lauren

Took a home pregnancy test after period was late two days and it tested positive. This was my first full month off the pill in years and first month really "trying". The doctor's office set my appointment to confirm pregnancy at Jan. 7th when according to this app I'll already be 9 weeks. We will do an ultrasound then too. Until that happens I'm so unsure if I should be relying on a little pee test to know If I am really pregnant. I haven't told anyone other than my husband and my best friend but my husband wants to tell family at Christmas. I'm so nervous to get them excited over a home test from the store. I'm reading all these stories of people having ultrasounds and doctors appointments much earlier than when my doctor set mine. Should I demand to go in and get a blood test soonee just for piece of mind?
