Waiting for the shoe to drop...

An

So my husband and I got a BFP this weekend with a line that gets darker every day. We are 4 weeks pregnant and so excited for an October 14th baby. But... it was only our first month of TTC so it feels too good to be true. I also found out this week that my sister had a miscarriage a few days ago, which makes me even more worried. How do you let go of the anxiety in the first trimester? Does it get better?
