7dpo according to this app

I missed my peak so I'm not sure when I actually ovulated, so I'm just going by what it says. According to the app I'm a week into the wait. 7 more days until I'm due for AF which I hope does not show up. I have been having off and on cramping since before and after ovulation. Today was worse. Not too bad but a little more intense. It happened after I went to the bathroom. I think it might be due to other things going on in my life that I'm feeling overwhelmed over (due to my own fault). I ended up having to use my heating pad to get the cramping that was on both sides to stop. It almost felt like it was my period, however I'm still a week away from that and I'm almost never that early, so I'm thinking it could just be stress getting to me, or implantation. Wishful thinking is what that is. It didn't feel like a stomach ache which is why I keep leaning towards it 🤷🏼‍♀️🤷🏼‍♀️🤷🏼‍♀️ anyone else experienced this?
