Am I seeing things?!?

Mandy • Hey beautiful baby-makers!! Just turned the big 30 and have been TTC for 1month. Can`t wait for that BFP!!
The first test was last night 8DPO (just a generic brand) and I read it about 15min after. Second test was this morning with first response at 9DPO at 5min. Am I just seeing things? Is the first test invalid because it was greater than 10min???
