Implantation bleed CD30

[lilyimogen]

For backstory
average cycle length 36 days - period is usually late. Like could be a week late and I wouldn’t be surprised.

Clearblue stated my peak fertility day to be CD22 - this is based on 4 months of tracking ovulation tests but only 1 month having 1 positive result

This months period isn’t due until 7/11.

On 31/10 I started spotting in the evening (a week early if it’s my period).
It’s now eve of 1/11 and it’s not gotten any heavier, if anything it’s lighter, like barely there. I’ve cramped for days now.
I didn’t get a positive ovulation test this month but I forgot to test on 20,21,23/10 and had unprotected sex on 26/10 (ov tests on 22,24,25,26 all negative)

could it be implantation bleeding?
the spotting started on what would be 7 days after conception which is making me wonder.

I’ve been testing ovulation just to prepare to try to conceive but the lack of positives have put us in the mindset of ‘let’s take any chance we can if the chances are slim’
im trying not to get my hopes up

A week early period makes me think potentially implantation. However implantation is extremely light usually and only noticed for one day! Ive never had it personally so only what I have read. I never had any last time.
Also another question would be do you experiences different times ie early late periods or are they usually bang on?

Thank you
with my first pregnancy nearly 10 years ago I had implantation bleeding but heavy and long enough that I thought it was a period and I was actually 4 weeks further along than we initially thought when we eventually tested because of that. It’s now 3 days of this and it’s gotten no heavier but the cramps are worsening which is making me think it’s a period

my periods have always been late consistently for a couple years now which is why it being a week early is bizarre
