Bulging head? 😕

I've noticed that my baby's head is larger at the front that it is at the back, almost like it's bulging, starting from the middle (at the soft spot) to his forehead , but the entire width across his head (not just a lump/bump).

Is this normal? I noticed it a couple of days ago and just assumed that it was normal after my MIL assured me that baby's sometimes have uneven heads for a while but the more I see it, the more I don't like it. He's 7 weeks/3 days adjusted.

Thanks
