Did anyone else have mild cramping... almost like a warmness not pain few days after ovulation? I have been nauseous since 7DPO along with the cramping, major neck back and arm acne (7 or so DPO as well), and bad heartburn/gas. Had what I think was implantation bleeding (streak of dark blood in discharge) at about 4 or 5 DPO. Oh yeah and I am moody as all outdoors.
