Hi everyone,

So for the past week I have had lower  abdomen cramps that come and go, breast tenderness, some nausea, and lower back pain. My next period is on the 22nd. Could everything I'm feeling just be ovulation, even though it says my ovulation time is done. I have never had this symptoms so intense and long before or haven't had them at all. Can they grow so intensely fast? Or could these be early pregnancy symptoms? My anxiety is making me go a little crazy waiting and counting down the days until I'm suppose to get my period. Thank you in advance.
