Top test (first response) on 8/4 was at 12 DPO & had a faint line. Then I tested again 8/5 at 13 DPO with 1st response again & got a much darker line. Then today 8/6 at

14DPO & day that AF is supposed to come I tested again with a cheap 88 cent test from Walmart & there is a very faint line... so I'm confused on if I'm actually pregnant or not!! Please help!!
