Implantation Bleeding, Yes or No?

I have not had any pms usual symptoms this month. My bbt dropped this morning (first month tracking) and now this bleeding. Usually my periods starts bright red. Pregnancy tests have been negative so far. What do you think?

My ovulation was supposedly Thurs 13th Aug and we had sex on the Friday so am not expecting to conceive this month. This was via an app and not actually testing to see if ovulation was indeed Thursday. But my app calculator has been very accurate in the past (however in June I did go on holiday and took the pills to delay my period so it could be out of sorts)

So today is Saturday 9dpo and 8 post sex and i have this. It was lighter yesterday, basically just pinky droplets of water it seemed like.

My period isn’t due until Thursday and i have never had early bleeding. My three other pregnancies (two successful) never had implantation bleeding so really not sure whether to even consider this as implantation and just it being an abnormal early period?

I’m currently abroad with my husband so we’re having a few drinks in the evenings, but now I’m unsure about what this is

Period is due Tuesday 25th, I’m around 10dpo today but I’m not 100%. (I was ovulating whilst on holiday and it was the first time in 18 months that I didn’t do any ovulation tests as I wanted to relax and just enjoy my holiday.)

Was due my period Friday but I’ve had this on and off for the past 3 days most times nothing when I wipe this was probably the most I’ve had and it’s only been red/brown and a little bit. Felt a bit sick on and off and been over emotional. Could this be implantation?

I just got my positive today , went to pee and was light pee when I wiped now I’m worried period wasn’t due for 3 days
