Implantation Bleeding?

Me & hubby have been trying for just over a month now. I get irregular periods. All day today I have been getting very light blood when I wipe (sorry if tmi). now normally when I get this i have a period after a couple of hours and I havent this time. I normally have very heavy periods. So could this be implatation bleeding? I can't find much on the internet about it so...if anyone could help that would be great. Another thing is I don't feel like im going to have a period.

Thanks Girls x
