I had a miscarriage at the end of May at about 6 weeks pregnant. I got a positive pregnancy test a day after seeing a rainbow in the sky. I'm 4 weeks 3 days based on my last period and I went in for blood work today and go back in Wednesday and am hoping for high numbers with a big jump! They did a sono but no one expected to see anything this soon and we didn't. My first response pregnancy test the line has been getting darker, but the nurse told me today I had a feint line on there test. Hoping for sticky bean!!! I love my rainbow already and this will be baby #2 for my little family!
