Am I pregnant again or no

Okay so this will be my second pregnancy, and my period stop the 23rd I have a normal five day period ! But on the third I took a pregnancy test, and it had a faint positive sign,so I took another one on the forth , and I had a faint positive and then I took one this morning and also had a faint positive sign. Am I pregnant and it's just too early for it to be dark or am I getting false positive I've been pregnant before so I know how it feels and I feel pregnant just not sure if I'm taking it to early !!!! Please help this is just one test .. am I crazy or is there a line
