How to enjoy a BFP after years of infertility

Jessica
Hi All! 
After 3 years, 5 IUIs, and 2 IVFs cycles on 2/5 we got out BFP! I've taken 3 more tests since and had 2 blood tests. Third is Monday 2/13 just to make sure my HCG level climbs over 1,000. 
Ladies who have had similar experiences... how did you move on to enjoy them? Candidly we have a great support group of family and close friends and I don't want to tell anyone! I'm so afraid this won't last. I think part of me doesn't even believe that I'm actually pregnant. 
Please share how you got through this! Thank you!
