Implantation bleeding

Hello,

I have read a lot of different things online about implantation bleeding. But for some reason with the two pregnancies I've had (both miscarried at 11 and 9 weeks) I have never experienced anything close to what is described when it comes to implantation bleeding. Today I am on day 25 of my cycle and I started to bleed a tiny bit. I had a miscarriage on the 8th of October and a full period on the 3rd of November. Could this be implantation bleeding or an early period? (My cycle is normally 28-29 days) Is it normal for implantation bleeding to occur this late in a cycle? Also, is it normal for cycles to be irregular a couple months after a miscarriage?

I know this is a lot of questions, just wondering what others have experienced because I had a doctor's appointment a couple weeks ago and won't have another for a while.
