How to/Can I surprise my hubby with a BFP after a miscarriage?????

Cassandra
My husband and I had an early term miscarriage a few months ago. Well, since I still get on here and read all the top posts, I was wondering how to do a surprise announcement to my hubby once I get pregnant again (hopefully!). I didn't do one with our first,  because I was so excited/shocked. I'm afraid to do a surprise announcement due to the pure fear that I get about losing another baby...  But I also want to try and not lessen our excitement because of the unknown. What's everyone's experiences?  I also wondered if I should wait till 6 or 8 weeks this time instead of 4 weeks like last time. It would be hard, and I'm just not sure!  Any advice would be great!
