Not sure if I should tell him or surprise him...

So I'm 5 + 1 today. I originally had an appointment for February 14th to go and confirm with the doctor and I was going to surprise my husband by bringing him because he doesn't know yet, but I've already known for about a week. Now my doctors appointment is rescheduled until the 26th 😑 . I don't know if I should tell him now or wait and surprise him by taking him to the doctors appointment like I had planned. I did have a surprise planned for both him and my stepdaughter that I was going to give them on the 14th after the doctors appointment. Should I wait or should I still keep the surprise?
