5-6dpo

So I had a bit of spotting on 3dpo but it would have been from ovulation or idk 🤷‍♀️ but today I’m 5-6 dpo my boobs are starting to hurt I’ve been soo moody and I’m spotting could this be implantation I heard some implant early. I also had a high opk but not positive but like 0.46 or something. I’ve been extremely moody way more moody then other cycles I’ve been trying for 8 months I really really hope this is it cause I never spit at this time during my cycle
