Line Progression Help!

Hello all! Please be easy on me! I lost our first pregnancy last year to a MC so I have become slightly neurotic after 9 months of negatives and finally got a positive last week. These are the tests I’ve taken, but for some reason I feel like the test line should be darker? I know HCG doubles every 48 hours or so and I took the blue one yesterday-but does it look like I’m in the clear??

My cycles are irregular after my MC and my LMP was June 5-my last two cycles were 27 Days and 25 days...anyone have a guess of how many weeks??
