Low hcg levels???

Lea

I should be 5 weeks 6 days pregnant today and have chosen to not have a scan until 12 weeks along, but I have had a missed miscarriage a few years ago so I am quite anxious so have been testing sporadically to satisfy my nerves and double check my hcg levels haven't dropped.

This morning I did a test and the line to confirm pregnancy is lighter.

I first tested at 3 weeks 3 days I believe, showing a faint line, the others were done 8 days later and the confirmation line was so bold that it drew colour from the control line making it appear fainter. This mornings control line is dark again and the confirmation line is lighter.... what do you think :/
