Fertility after MC?

Br

My hubby and I had a MC in May after trying to get pregnant for 10 months. We waited until my body was healed and started trying again in August. We have been tracking my ovulation through BBT and OPKs but sill no luck. Where do we go from here? I’m 29, hubby is 37. Neither of us have been ‘tested’ which is a question I have been getting recently. I don’t know what people mean by this. What should we be getting tested for? Where do we get tested? Is this something my OBGYN can do for us? Any tips, advice or answers will be a big help

Baby dust and love to all this holiday season ❤️✨🌟
