5 days ago I took a first response. I thought i saw the start of something but I posted it and everyone said negative so I didn't worry with it. well today I was cleaning my bathroom and noticed the test had two dark pink lines?? I know out of the time frame it's invalid but has this happened to anybody and you actually were pregnant? I've had symptoms and my period for August was MIA. Supposed to be due for September around the 17th.
