How to support my wife

My wife is early in pregnancy and she is starting to spot brown . We had a miscarriage back in 2016. We both got real bad depressed back then . We are now 30 and have our 1 year old rainbow baby . This was a shock when she said she was pregnant because we had to do <a href="https://glowing.com/glow-fertility-program">fertility treatment</a> with our son . I just want to be supportive if it happens. Any advice ? I don’t believe a woman should go through anything like that alone
