Need Help & Opinions!

I took a clear blue digital test last night that came back

positive! Took a couple more an hour or so later and they

came back negative!

This morning, I took an equate early response test and

got a faint line!

I've been cramping and spotting these last few days also.

My husband and I had unprotected sex on August 11, so

don't know if it may be too early for all the tests to come

back positive? Or if it is common to have a false positive

digital clear blue?

Any help/insight would be very appreciated!
