Lh surge late AF

Je

Hey ladies!

What’s the deal with LH surges right before Af? I’m currently 2-3 days late, negative pregnancy tests although last week I had some faint lines which were probably just evap lines..

If LH spikes could I possibly still conceive this late and have a normal period (if that even comes)? I know you can ovulate late, but not sure if you can still conceive this late since there technically wouldn’t be a long enough lutheal phase??
