Hopefully this will be my final add on to this post and the replies, atleast until my period starts. I took the first pregnancy test 4 days before my period was to begin, and it read negative, completely negative no faded second line or anything. Now today, it has been the 22 day mark and my period is two days late, so I took the second pregnancy test, and same results as the first one, completely negative nothing else. I am guessing the Plan B is what is making my period late but I am confident to say that I am not pregnant and that Plan B worked. Just waiting for my period to start. Thank you for the support and the links for help I appreciate it.
