Mayra

Hi everyone, so my last menstrual cycle was July 18-23rd, we've been TTC since then... today is Sep 19 and its cycle day 64 and I still have not gotten my period, I've taken pregnancy test and they have all came back negative, my big thing today is that I went to the restroom and and I felt wet, I inserted my two fingers and when I pulled it out I had alot of watery clear strechy cervical mucus!!!! Like the beautiful fertile kind that everyone talks about.. I've never had so much like today, but how can that be if I'm 64 cycle days in??? My periods are irregular, and I really do not know when I ovulate... could someone please HELP ME could I be ovulating this late???
