Advice: What Doctor to call if TTC a year?

Becca • Newly pregnant through IVF, after TTC for two years.
I need help with the basics...
I'm 33, we've been TTC for a year. We've done digital OPK, preseed, and I have a year's info written down.
We need some help.
What Doctor do I call to make an appointment? OBGYN? GP?  Infertility clinic? 
What do I say we need an appointment for? 
Anyone else ever feel weird calling a doctors office and relaying personal medical info to the office people who run the front of the house who aren't doctors or nurses? 
Do DH and I both go to an appt together? 
Someone please fill in the details for me 🤓
