so I have not had a period since October and my period are regular normally. usually get period 16th through 25th. I missed my period in November and I did test but all neg. it's now December 8th and i still haven't gotten my period or or any sign of getting it that I usually get. I did end up having a kidney stone but I'm having pregnancy symptoms. is there a chance I'm pregnant? my boyfriend and I have regular unprotected sex every day. according to glow my period should be coming on the 16th.
