Pregnant After Miscarriage: Need Advice

I just need some words of encouragement .I'm currently 18 weeks pregnant with my rainbow baby .I miscarried last year and it had a huge impact on my views of having kids .I never thought I could have or keep kids after it but now I'm almost 5 months pregnant .wayy longer than I was pregnant last time .I've just built up a lot of anxiety .I'm worried I may end up being high risk or even might have another miscarriage. is anyone going through this and can you please give me advice??
