Line progression

Nicola • Married. 29 years old. Mmc at 11 weeks July 2015 and mc at 4+3 weeks Nov 2015. Pregnant with baby girl due 30.07.17 ♡♡
I had a mmc in July at 9 weeks. I'm now 4 weeks pregnant with my rainbow baby but worried my lines aren't getting much stronger. Does this look ok for 9-10dpo? I'm so scared of losing another baby and worried my lines aren't very strong and it's a sign of a weak pregnancy x x
