Mmm ? Advice ?

JM • 28 started TTC #baby 1 June 2016. 2 and half years 🌟
Did a clear blue plus a faint line showed up, 
But did a strip test a cheap one from eBay and negative. ??? They've all be negative the cheap strip test. 
But got the clear blue today did a test and got a faint line ? Was blue tho. I was due for AF 27th. It's now the start of the 30th. 
I'm never late. Could it be a start to a positive? 
Clear blue done in time frame of 2 minutes
