Implantation cramping?

So i believe i may have had implantation cramping at 7,8 and 9 dpo. It started off as mild pinching sensation to period like cramps. On 10 dpo through now 12 dpo I've felt fine besides bloating, on and off tugging feeling, back aches here and there and extreme fatigue today. Has anyone ever experienced this and ended up getting a bfp? My period is due in 5 days and dont normally cramp way before then.
