Normal or possible chemical?

Lea

So yesterday morning (11dpo) I got a positive on a first response test with fmu. It was light but still there.

This morning I took another first response and fmu to see line progression but it’s about the same lightness, and weirdly the test and control line aren’t as narrow as yesterday’s test? I’ve had a chemical and a missed miscarriage before my first daughter and now this makes me think it’s gonna be a chemical. What do you ladies think? The top one is from this AM, bottoms is yesterday. Both today and yesterday it showed but very faintly on two different cheap brands too
