I can’t believe this is happening again

I had my son in July 2020. Totally normal. In august 2021 I had a miscarriage at 8 weeks. I just found out two weeks ago I’m pregnant again and my numbers went from 51 to 145 in two days; beautiful! They sent me back 8 days later for another round and my first number is 589. This is way too low for an 8 day spread. I cannot believe I’m going to lose another baby. Two in a row? I can’t imagine this being a positive outcome and I’m so devastated. I’m so angry at myself for letting myself get excited. I just want to give up trying anymore at this point.
