Evan line, Possible IB or early period?

[Mam2one]

Wonder if anyone can shed some light... I usually have a 28day cycle and was surprised to see AF arrive unexpected on cycle day 24. It was very light at first more like spotting then yesterday a bit darker and more like AF but not as heavy. Also had an on/off headache for the past 5days.

We DTD on cycle day 18 (going by an app thinking I would have ovulated by then) and had my last AF on 1/08. However, I just feel off and decided to POAS. I don’t know if this is a faint line or a dodgy test. Can anyone else see a line. Anyone else been through something similar and got a bfp? Actually losing my mind here.

Sorry above should say ^Evap line*

I think I see something, but I can't see if there's colour in it or not. But when I calculate correctly - you DTD on CD18, so ovulation would have to happen around that - then you're earliest 6dpo, which is very early. Implantation can happen as early as that, but mostly it's around 9dpo. I'm sorry I think there's not much you can do but test again in a day or two to see what happens?
