Please help — test lines darker after what I thought was a chemical

At 4 weeks and a few days, after several positive tests that were not getting darker, I had heavy bleeding with clots for 4 days or so (8 days ago). I assumed it was a chemical pregnancy.

Today I took an ovulation test to get a baseline and it showed I was having an LH surge which doesn’t seem right at all, it’s only been 8 days since the miscarriage.

So I took pregnancy tests and the test lines are by far the darkest they’ve ever been.

Could it be ectopic?
