Possible implantation bleeding

MOXIEKAT • .............
I woke up this morning and noticed sharp twinges on my left side which has continued throughout the day. I'm now getting random period like cramping and light brown spotting when I wipe. I'm due for af on the 11th. I'm hoping this is implantation bleeding. We dtd almost every day during my fertile cycle. I'm resisting testing until I'm officially late, but I have to admit, my hopes are high.
