Implantation bleeding?

[FutureMrsD]

Hi all,
Very new to this all!
Last period started 29th Jan. On Sunday AF will be 4 weeks later.
Had really intense cramps on Monday into Monday eve (worse that normal period) but I was thinking that that was AF on her way.
Put in a liner to can see that’s occurring, all day yesterday had the tiniest little spot (like not even size of 5p) and then again over night, tiny spot. Very dark brown in colour; maybe this mornings a little redder.
Has intercourse on 3rd, 9th and 17th if this helps.
Was this implantation bleeding do you think? Or is my body just a bit confused and chucking out some dark discharge for fun?
Skin also broken out and I’m a little moody, but this could obviously mean either!

Have u taken a pregnancy test?

Yes, yesterday morning, but it was negative.

Forgot to add, nothing today so far..

If ur last period was 29th of jan it would too late for an implantation bleed and I would of expected you be be around 8 weeks pregnant depending on your cycle length.
So if your test yesterday was negative I would be sure you r not pregnant.
I would probably arrange a trip to the gp to look into why your period is so late.
