Has the line got darker?

For context I had a miscarriage about 3w 5 days ago.

So my hcg has been going down.

I have been very sexually active the past 2 and a half weeks pretty much everyday so I think I could possibly be pregnant again?

Do you think the line has got darker since Wednesday or is it possible for it to be up and down hcg?

Or do u think this is a new pregnancy

Both taken around 12.30pm
