13DPT line progression on FRER?!

Hey guys,

I am 13DPT for my first IUI, probably 11DPO

I took an easy@home year two mornings ago and it was almost non existent, it’s gotten darker since then so I’m pretty sure it’s not the trigger

Yesterday morning I also took a FRER and I did this morning too. The line is there but isn’t getting any darker, same with my easy@home. I’m worried about a chemical of course.

I know the only answer is to keep testing which I will, but do any of you think you see a difference in the tests? Also did you have slow progressing FRERs that we’re still a BFP??

Here’s my easy at home 9DPO top to this morning 11DPO (13DPT) bottom

Here’s my FRER too 10DPO, bottom 11DPO BOTH FMU
