Help!!! Chemical?

The top test was taken Sunday 2/25 (2 days before missed period.) with 2nd morning urine (around 10:30am)

The bottom test was taken this morning at 5:20am. So two days apart- I don’t think the line is getting any darker. Today was the day my period was due.

I am terrified that this is going to be a chemical pregnancy. Has anyone had any faint positives on the day their period was due and still had a successful pregnancy?

I had a m/c at 13 weeks 3 days on November 1. And the last time I got a negative the day before my period was due and a blazing positive two days after.
