IB or AF??


I know Implantation bleeding is common 6-12DPO, I’m 13DPO today and have mild cramping and saw this. My luteal phase is 14 days long AF comes 15DPO. I only spot the morning AF comes and within hours I get my period. I’m guessing this is AF but my cycle is usually 33-35 days and today is CD32 for me.

I also have had weird nipple sensations which is never something I experience before AF, but I know it’s common. My temp did drop a bit this morning but it’s still above the coverline. Idk what to think? Anyone experience something similar? Any ideas?
