Faint positive on cheap Walmart tests and BFN on FRER?! Am I pregnant?!

[JBsWife]

I had brown spotting 4 days after what I believe to have been the day I conceived. That lasted for 2 days, and only when I wiped. My period is now 4 days late and in the past week I've tested with 2 Walmart cheap tests and 2 CVS cheap tests and all have had a faint positive line within the result time, with the last one that I took 3 days ago being the most noticeable of the 4. Then this morning I took a FRER and it was an obvious BFN, no sign of a second line what so ever. Could those cheap tests have been wrong or is there a chance my HCG levels still haven't risen high enough? Thank you so much for your help!

I've only used cheap tests for both my pregnancies and they always were right on. Try waiting a few days and test again? Fingers crossed for bfp.

Were they all pink dye tests? I know some women get better results with certain kinds of tests, but FRERs have always been the ones I trust the most. FX for you!
