Line Eyes, Please?

Hello. I am almost 37 and have never encountered this before. I have always had very clear negatives. I sadly haven't been tracking for the last two months due to some other personal things going on but my LMP started 8/18 and I did happen to check LH during my O window and peak days were 8/28 & 8/29. I did the pink dye test on 9/11 and the clear blue on 9/13. I swear I see something on both but I took FRER today and it was very negative. Thoughts?
