TMI-pic in comments-opinions needed ( sorry long post)

So my Cycles are always pretty normal aside from normally being a day or two later than projected dates. What can I say AF likes to show up fashionably late. This months EP was 1/22 or 1/23. ( Always late never early) She arrived the 21st. First day was like a regular period, first thing as I awoke she was there( AF doesn't show up till mid morning after I've moved around,cramping a little spotting then flood gates on first day). My period generally are heavy days 1-3 then light. My period this month was 1 regular, 1 light and 1 1/2 a tampon of blood by 12pm and done period. So 2.5 days. No blood at all yesterday. Cramping last night with CM ( I'll post in Comments). Cramping again this AM, still light cm. I don't get it.
