me and bf use withdrawal and condoms and have sex often well i have a weird period its usually 35 -36 days give or take days...now im 8 days late never been that long, and lately ive been getting tired alot and can barely wake myself. Headaches, dizzy and alittle crampy but thats it..nothing else..at all.. usually before my period i have strong pms symptoms...should i test? Or give it another week? Could i be pregnant?
