7, 8, & 9 dpo

Hey yall, I've been having menstrual like cramps on 7, 8, and 9 dpo. 7dpo was very mild and felt odd, like a dull pulling feeling, and only lasted maybe 30 minutes. 8 and 9 dpo I'm having dull menstrual like cramps accompanied with (TMI) loose stools (not diarrhea, just loose) I haven't seen any tinted cm or anything to indicate implantation bleeding. My period starts in 7 days and I don't typically get period cramps until the day before I start... what do yall think?
