Implantation bleeding?

I am 7 DPO. I went to the bathroom today and noticed a pink tinge to the TP when I wiped. I’ve been a little crampy but not bad. Is it possible this could be implantation ?! My period is due to come October 3rd. I honestly kind of just told my fiancé just last month, I’m done trying so hard. I’m done LH testing. Just done. It’s such a disappointment when you’re older and things, like getting pregnant the first time, just don’t come east anymore. So I just stopped worrying so much. It would be so cool if I ended up pregnant this month!
