I Stopped taking BC 2 months ago,but my period became regular immediately (25 day cycle for me).  Last AF began on Jan 14th, should start again on Feb 7th. I've been having unusual symptoms: I  had sex day before ovulation and 2 days after (we use withdraw method). I am now 8dpo. Been having mild, lower abdominal cramping and weird muscle twitches down there, constant headaches, moodiness, super watery and excessive CM.  Does this sound like anything, or am I maybe just PMSing??
