Feeling so lost. Please help me.

My husband and I tried for just over a year to get pregnant. I lost my mother the day after Christmas and found out I was pregnant the following month on January 24th. We were so excited! But on my first appointment, my dr said “there’s no heartbeat, there’s probably only about a 10% chance that this pregnancy will stick”. My husband and I were shattered... today I got an emergency ultrasound and they found our little bean’s heartbeat. But they said it was far to weak. They told me to come back on Monday and if the heartbeat doesn’t get better, then it will likely result in MC. I just don’t know what to do. Baby is measuring perfectly, 6 weeks and 1 day. I really really don’t know what to think. I keep praying for my little bean, but I feel so defeated.
