Preg test

Cerys

Hi all! Want some advice, I took a preg yest yesterday which had a positive line, was very faint! So I did another and was again the same faint line but was deffo 2 lines. I took another test this morning first thing which came up negative. But have since done a test which come up with a just about the second line. My period isn’t for another 16 days! Am I going crazy or is there 2 lines here?! Any advice?? Xx
