10 or 12 dpo bfn 😔

Amber

Had deep cramping only on the left side that radiated to my hip and thigh yesterday (9 or 11dpo)off and on for about 4-5 hours. Took a cheapie tonight and bfn feeling out. No symptoms today except nausea & (tmi) some diarrhea this morning. No cramps. Very itchy breasts tho. Any hope? I ovulated on Feb. 17th or 19th. Period due March 3rd-5th
