Misscarried Before Pregnant Again

Scout
I misscarried in December extremely early. Right after I took the test actually. And now I am pregnant again. I'm 7 weeks. My boobs are bigger and my nipples tingle and I'm peeing a lot BUT in the last week those symptoms have lessened. I have a bit of light cramps too. No bleedong or anything. I have a doctors appointment on Thursday my first one actually. I'm just nervous something is wrong. I've told family this time and my heart would just be shattered all over again. Any positive advice or insights would be lovely. Thanks in advance.
