Faint test results

Tmg

Hi,

So 2 weeks before my period me and my husband tried to conceive, took a test 2 days after my period was late and test came out positive,then I took another test to be sure and it was negative, and the 3rd day I got my period, I took another test and it was negative and just now took another and it shows positive and the lines are faint, I got 3 out of 5 test positive, and the first time came out dark and clear and the other 2 are faint... can anyway help with this?
