So I took a test on the 6th and it came back positive with a very faint line. Supposedly, if I am pregnant, my egg is being implanted in my uterus this week... I've been having really sharp pains on the left side of my abdomen... Anyone else have these for the same reason?? Or would it be of something else? Like, is that normal? Is there even such a thing as implantation pain??? Lol!!!! Help!!
