7th pregnancy (1 live birth 5 m/c)

After 4 years of tct I had my now 4 1/2 year old daughter and have had 5 m/c since her. They were completely unexplained and all were lost after 9/10 weeks. I have tried everything but <a href="https://glowing.com/glow-fertility-program">ivf</a> to get and stay pregnant since. Back in November I got a positive. I am now 13 weeks along with good ultrasounds and checkups under my belt but I am still petrified to tell anyone, especially my daughter. I feel like my husband and I can’t agree on who to tell and when to break the news. I’d like to wait till halfway when I can’t hide it anymore but he is ready now. What should I do?
