Possibly pregnant or early period?

Okay ladies, so I’m a bit confused. I’ve been wanting a baby for a while now and I think this may be my month. This may be a bit tmi, so my apologies. Today, I’m 10 days past ovulation. I started to notice period cramping when I was 8do. Yesterday was the most noticeable day for the cramping. My period isn’t due for five days, so it’s unusual for me to start cramping a week ahead. On top of that I noticed my nipples were slightly sore but I’m honestly not even wanting to symptom spot. Well today, I had a little self pleasure session lol and I noticed when I went to the bathroom some slightly brown clumpy discharge. It was barely noticeable. Has anyone else had this, and do you think it’s possibly implantation?? Thank you in advance ♥️
