could i have a minute of your time to put my mind at rest? pics included

Hi I've been with my partner almost 3 years and TTC now, got my last period on SATURDAY 27th SEPTEMBER & due to work comittments this month we didnt get as much time together as we liked but there was a couple of times around ovulation. I was due my next period on SATURDAY 25th OCTOBER & i usually have a pretty regular cycle, Yesterday (making me 4 days late) i was getting cramps, so kept checking myself and use white toilet paper there for the evening. Little pink brown droplets?? I was panicked thinking it were the start of my period but it abruptly stopped? And nothing since Id done a negative test that morning also, Could it have been implantation? But why so late in my cycle at 4 DAYS after my expected period, Got sore boobs & SEVERE bloating but thats it? Help?
