So I took a pregnancy test on the 12th knowing that my period was due for the 14th and I got a faint line this was a first response then two days ago I took a Walmart 88c test and got a negative.... now I'm several days late on my period and am having every symptom under the sun what do you guys think it is?? its not very clear but there is the first response faint line.
