Help? Worried mom to be

Sh

So worried, its my 1st trimester and im cramping on the left side really bad and its going into my bacj. Is that normal or should i really really worry about ectopic pregnancy. Or am i just overthinking it. I dont have medicaid yet im in the process of getting it and my appt with them is Monday then im good to go to the doctor but its so far away and im worried NOW.😫
