Can an ovulation test detect pregnancy before a pregnancy test?

So my period was 4days late which was unusual and it was pretty light. I had 4 days spotting following this which isn’t normal for me but I didn’t think anything of it by that point. I just thought it was the tail end of my period.

When I started my ovulation test I got a couple negative and then two ‘high’ readings. Today I got my peak after only two highs. I appreciate that it can vary but this is very different to my previous cycles.

I took a pregnancy test and it came up negative.

My question is whether an ovulation test can pick up pregnancy before a pregnancy test?
