High levels of fluids

I saw my OB today and he told me I have a high amount of fluids in the sac and there’s a high possibility of miscarriage. I am having twins and they are growing well at 9 weeks. Heart rates of 175 and 166. I saw them 2 weeks ago at 7 weeks and their heart rates were 165 and 170. I see my OB again in 2 weeks but so frightened of the words he said today. Does anything have any success stories of high fluid and having a healthy pregnancy? Please give me hope. My heart is crushed ❤️‍🩹
