I am not on the pill , I am 43 years old, typically get a period every month . I had sex on Sept. 11(there is a possibility that the condom broke) didn't get a period until Oct 1st it was not a heavy period nor a long one(so no period in September...last period was August 22nd). I had a week and half of cramping on and off, extreme fatigue, lightheadedness before I finally started bleeding ,this cramping ,fatigue and lightheadedness are not normal symptoms for me. Even though the bleeding has stopped . The fatigue and lightheadedness and have not , could this be a hormonal imbalance? if it is a possible pregnancy, when would be the best time to test?
