?Implantation bleeding

I am 27, this is my 6th month TTC after I had my left tube removed due to ectopic pregnancy. I have been getting regular 31 day cycles since this happened. This month, I ovulated late (confirmed by progesterone test) and i had spotting for 5 days with af cramps around ovulation. I am currently 10-11dpo. I figure my period is supposed to start in 5 daysish, although who knows. Today after doing the deed with hubby, I got this....could this be implantation bleeding or just irritating my cervix? Or maybe my flow is starting now.
