TMI!! Is this start of period or a good sign?

[Emcait07]

So I don’t have regular periods at all.
Iv been ttc for 4 years and this month Iv had 4 days of cramping first day being very strong cramps almost stitch like pain when I made sudden moves.
Iv had ewcm most of these days and it’s been streaked with pink today when I wiped it was more then usual and I havnt experienced anything like this before a period.
Could it be just my period starting?
I litrally have no idea how many dpo iam or if I even ovulated but I’m currently cd60 usually range between 42-55 days.

Honestly, it could be both. Either AF starting or implantation bleed. Have you tested? You could always just test to see if you get pos. result or wait 2-3 days after this bleed. If it was IB, then you'd probably get a bfp in 2-3 days.
