Implantation Bleeding?

It is CD24 for me. I usually have fairly long cycles ranging from 32-45ish days. I have been having pelvic and stomach cramps periodically throughout the day. After dinner they got worse to where I thought I might have to have a bm. I went pee and when i wiped I noticed lots of spotting. Do you think this is implantation bleeding? or maybe ovulation spotting? I had creamy cm earlier today. I am not really sure what to think of this. Hubby and I have been trying for over 2 years and I would love for this to turn into a bfp!
