I need help!!!

Okay I had my period 3 days early on the 23rd. 4 days later it lightened up and I took a pregnancy test the 22nd and 23rd and it was a faint positive. I took another test today the 29th 2 days after my period was done and it still shows a faint positive. What do you ladies think and what should I do? This has never happened to me and this test is darker than the one I took on the 22nd and 23rd.
