3 weeks 5 days pregnant with my rainbow baby !

We lost our precious baby at 9 weeks 3 days in February and have been trying ever since to get pregnant .I am so scared ! I am not feeling as much excitement this time and in a way preparing myself for another loss . I work part time as well this time around and my job consists of standing for long amounts of time 8:30-2:00 I'm hoping I can make it :) Does any rainbow mommy's have any advice ? My test is sooo light since I am only 10 dpo .
