Help! Ttc

We have been trying for baby #2 for almost 2 years now, tracking and everything. In the past 3 months I’d have two periods a month. I have thiugh made a appointment for that.

Today (2 days before my period) I lightly spotted, never anything on the pad, but only when I wipe it would be light pink. Could it be implantation bleeding? Or likely just my period coming in? I have had on and off lower cramps and a migraine towards the end of the evening.

Peeing so much these past couple days & only wanting to snack!

How soon is too soon to test?
