help?!

Kayla
This was my feb log, however I was supposed to start my period march 3rd and I still have not. I plan to test this morning but my fiancé an I had sex today and after we finished and I went to clean up I wiped and it was faintly pinkish but only on the first wipe. If I wasn't paying attention I wouldn't have even noticed could my period be coming or is this implantation signs?
