Did anyones test take long to get darker and still got bfp?

These are my test from a day or so ago that I posted. Brief story : I got bfp on 10/10 five days later had a oink spot then bled for two weeks and 5 days, we thought it was an mc . After bleeding stopped I test and got bfn the five days later got these. Tested this morning and its still vfl. We did the twin protocol. We go to the doctor Monday I'm so scared.

note today's test in comments:
