Spotting 5 days before period and then it stopped?

I am not using any birth control at the moment.

I was on holiday and had went to the toilet just to pee and when I wiped there was pinkish blood on my tissue...

So i assumed it was just my period...I wasn’t due on for another 5 days.

The spotting turned brown by the next day and as I was using a pad, when I went to change it nothing was on it...the spotting was that light.

So since then I have had no spotting whatsoever and have had light cramps.

My period is usually bang on 26 days or a little late...but its never been early and its never started with spotting and then stopping all together...

Could this be implantation bleeding? My period is due in a day and I dont know whether to test or not...?

Also to add I have been horrendously moody my poor boyfriends been suffering and I have had head-ached and broke out with spots....

What do you guys think?
