Walmart cheapie

I took a easy @ home test two nights ago which was faint positive. Of course I couldn’t wait to test again and tested clear blue digital which said not pregnant. I also have to add that I drank lots of water before which I probably shouldn’t of. Then today I took a Walmart cheapie which looks like this. I don’t really know how many dpo I’m because I took vitex which made my cycles longer. My last period started October 14th and I last BD on the 29th…is this line too faint ?
