This month has just been all over the place.. I have been very frustrated with my opks and I am still waiting for a temp spike to confirm ovulation. Yesterday I starting spotting (cycle day 16 I usually range 28-30 day cycles) and have been having cramps.. And now this morning I have some pretty strong cramps.. Here is my chart.. Are the spotting and cramps just from too much bd or ovulation or what?? any input is greatly appreciated
