No progression with FRER, but progression with walmart cheapie?

Due date would be 2/25. Confident of ovulation day as I have severe pain on day of O. *Maybe* a day off, but not likely.

Tests seem really light considering my DPO, but more concerning is FRER is not progressing in a way that indicates a viable pregnancy. Walmart cheapie (First Signal) seems to be progressing.. 11 and 12 DPO tests are definitely darker.

My strongest FRER test was a mid day slight urine hold at 11 DPO (test that says 11 DPO MID) but at 12 DPO FMU the test is as light as my 9 DPO FMU test.

Again, the walmart cheapie is getting darker.. What’s your thoughts? Tests checked immediately, at 5m mark, and at 10m mark.
