Infertility testing

Mary 👶🏻✨Fairy • Happily married 2 years, mommy to a 2 month old ❤️
I've had a ultrasound of my uterus & ovaries, they've done some blood tests I don't remember which ones. Every test my Obgyn has done has been normal. 
Hubby's had his sperm Analyis ... Motility is a little low 
Im curious, if we go to the fertility clinic.. What other tests would they do? Thank you in advance
