Pregnant right after Mc

Has anyone else gotten pregnant right after a miscarriage? I had a mc 9/29, and now I'm pregnant again. I was only 4w5d last time. I never did get my period, so I took a test. I keep taking test to make sure the line gets darker. Here is my test from this morning. I'm not sure how far along I am. I'm between 5-7 weeks. This was not even fmu. I've never had the lines be this dark!!
