+ FRER but - FR digital

Update**
Confirmed PREGNANT with bloodwork!!!
Is it okay that I got another faint positive FRER (the test lines are pink) and Internet cheapie (not shown) with FMU but a -no on the FR Digital with the same urine? I read that it's the same sensitivity... I really want to surprise my husband tonight but was wanting to do so after I got a +yes. Thoughts?
11 and 12dpo, photo taken 5 minutes after 12dpo test taken. Test lines are pink and these tests are from different boxes
