I am 1 month late of my period I didnt have my period on oct. I took maybe 5 to 7 pregnancy test all different days and came out negative until now still negative. I dont know if theres something to do with my anesthesia when I had my root canal done and another anesthesia when they put the temporary filling. I don't know if there something to do with that. I don't take birth control. Can you guys please advice me if this is normal or not. Thankyou..
