After miscarriage

My husband and I have been TTC for almost two years and this September after see fertility specialist and taking medications, IVF, and countless test we got pregnant naturally. But the the happiness was short lived or 8 weeks ultrasound showed no heartbeat so the pregnancy was terminated. 😔 It was heartbreaking and my husband was beyond devastated. So now we are back on the road of TTC and I’m debating that if I find out I’m pregnant in the coming months when should I tell him, he did take this loss well at all and I don’t want to get his hopes up again just to be let down. What do you think.
