Vvfl?

Hi everyone. Had my third loss in August so ttc again. Does anyone see a vvfl? I’m 13dpo so I’m worried the line is very light - I’ve never had a chemical before but my feeling is that this is going to be one? The tests are 25miu which may also be why the line is quite faint? I believe I implanted a little late on 10dpo. I’ll test again on Thursday but I just wondered if anyone else could see the line? If you have any similar experiences to share I’d be very grateful.
