Time to start testing 😟

My so and I have come to the point to start testing for infertility .... It makes me sad to think something is wrong with and scared. I also don't know the process or the steps to take so far my obgyn told me to get flood test done, and send a sample of so sperm! Not sure if I should do it through my obgyn or make an appt with a fertility clinic.....my obgyn just does the testing part then they hand you off to take care of everything else. Just so disappointing
