AF due around the 15! 9/10dpo. Please read!:)

Hi,
Yesterday morning (9dpo) when I woke up I checked for my CM (as I am nearing the end of my TWW soon!) and noticed some watery pink discharge. Very soon after I started feeling AF type cramps (mine are never THAT bad but noticeable none the less). I put a panty liner on because I just assumed AF was coming early. However, the day went on and that was all the spotting I noticed. The cramps lasted until the afternoon and I still felt bloated into the evening but I didn't see any other pink discharge. I know this COULD be implantation but my cycles can throw me for a loop from time to time (I had a 25 day cycle last month, before that 29 days!). Today at 10dpo the bloody pink discharge is completely gone. I have still felt a bloated feeling though and am still skeptical of AF arrival.If it was AF related do you guys think it would be continual spotting until my period was full on? Or can it be stop and go?
I appreciate all answers!! Thx!
