Yes or no??

I'm 14 dpo today and am starting to get nervous! My husband and I have been praying so hard for God to allow us to conceive in His timing. I'm trying to not get excited because I've read so many things online and know that chemical pregnancies are a thing. What do you guys think!? How soon will an OBGYN usually allow you to come in to get your blood work done to confirm? I'm lost!
