Implantation bleeding??? Please help!

Jazmin
Sorry if I'm posting in the wrong section?
I was at peak ovulation on the 29th of December. So for the past few days I've been getting on and off cramping. Also for the last 2 weeks or so I've had pimple come up on my face, when I don't usually get pimples. And my nipples have been SO sore for about a week and a half now. 
I just went to the toilet and I had a streak of bright red blood and light pinkish see through discharge, could this be implantation. Bleeding? I was due for my period 4 days ago. 
Please, can some one give me advise? 
What does implantation bleeding look like? I have no idea 😣
Thank you 💜
