Diluted testing trigger 10dpo

Ok its a confusing one. I had a trigger injection 11 days ago. Ive started testing out the line with 2MU. Days 6 & 7 were light but most definitely there. Didn't test 8. Day 9 was almost gone (really had to hold it in the right light to see it). Today day 10 was the same as yesterday. Ive just taken another this afternoon after a 2 hour hold (urine only a little bit more coloured) and the line is very prominent. Would you trust this?
