Has anyone ever done this? I'm 99% sure I ovulated on CD 13, and I have a ton of OPKs (cheapies) left over and have been using them just so I can POAS since HPTs are coming up negative still. I know that we always have some LH in our urine and that there will almost always be a second line on an opk, but my opks have been pretty dark for the past couple of days. Today's I would consider positive. So, what does that mean? Did I not ovulate and now I am? Is it turning up positive because I really am pg? I *maybe* had a faint line on an HPT this morning, but it's so dang light that I don't know if my eyes are playing tricks on me.
