I had had 4 first response positives and also a tescos own brand but clear blue digital said not pregnant am I or arnt I??

Go to a Doctor and find out.

Why did you take 5 tests and not believe the first one or two?

As I only had my inplant taken out 6 weeks ago and had three days spotting in between so seems surreal, went to doctor who refured me to midwife but didn't do bloods just still so confused?

4 positives negate the negative. It's very rare to get a false positive, much less 4. It's not at all rare to get a false negative.

If you're still unsure, go to your doctor for a blood test.
