Pregnancy test and hcg levels

When I first tested my hcg through blood my levels where only 29 with a positive pregnancy test with a pink faint line I’ve done these the last few days is it to say that the hcg levels are going up by these pregnancy tests the last one is taken out from a first response Yes + ?? Your opinions would be great , do you think this is progression from my first ever tests

First tests when levels were only 29 by bloods

The weekend just gone 3 tests darker ? Do u think my levels have gone up by this and it’s it definitely a pregnancy continuing
