Feeling guilty

Today I had my second OB appointment for them to do blood work and test and whatever else. Anyways my husband didn't go with me since he had work and i thought they wouldn't do anything since my doctor is a prick. However he went ahead and had us listen to the heart beat. Now I feel so guilty because my husband is so excited about this pregnancy. I almost don't want to tell him, but I know that would be so wrong of me. I was going to video it but my phone was also dead at the time 😟 I don't know what to do or how to tell him without having him get so bummed about it.
