Positive pregnancy test then negative

Sophie

So on the 24th June I had a faint line on the east at home, the 24th night had a positive clear blue and yesterday had a positive on first response and a positive on the conceive plus. These are all faint lines I’ll pics. Also think I had implantation bleeding and suffering with nauseous.

But I’ve had multiple negatives too I’m 3 days before period what do I do when shall I test again?
