12 dpo. symptoms

I'm 12 dpo. I've been cramping off and on since 7dpo. Like pulling twinges in my right side that last a few minutes. I've been peeing a lot more in the last two days than normal even without drinking much. I feel way different than I usually do with Af due Monday,  but I'm still testing negative.😭😭😭 does my calendar even look promising? I gotta positive OPK on January 8th.
