Dident tell him the truth

I had a misscarriage 3 days ago I was bleeding so bad I begged my husband to take me to the er. I told him I had a migraine and I was feeling dizzy. So when he finaly took me I had a blood trancefusion and lots of fluids and pain killers. I asked to just be discharged when they got the bleeding under control. My husband was in the car with our son and has no idea that I was even pregnant I don't even know if I should tell him.
