Hcg level reassurance

I feel like a lot of us (especially those of us who have experienced a mc) are really worried about our hcg levels and always want to know if we're normal. I found this link that allows you to type in your test results (must have two numbers) and the hours between tests and tells you if it's considered normal or not

​Unfortunately you will probably have to copy and paste the link but I feel it might give some of us some reassurance ☺️
​Wishing all of you lovely ladies a happy and healthy 9 months
