Sooo about a week ago, I took a pregnancy test because I was feeling some symptoms. It looked like a very faint line so I had put it away and forgot about it. While I was on a trip, I took a blood pregnancy test and it had came back negative. (Still had nausea and other symptoms, even though it had came back negative) HOWEVER, today I came home and remembered the old pregnancy test.. looked at it and then this happened !!!!!

Does anyone have any idea how could this happen ??? I’m really nervous any advise helps. Thank you
