Im officially 14 days past my af date and ive took several test and none has came out positive. My cycle is regular. My fiance called the obgyn for me and they said i should wait till the weekend and take another test. My primary doctor doesnt want to see me until nov 22nd. So should i wait till the weekend is up and see the obgyn or wait for my doc. Ive been dizzy like crazy,cramps and fatigued.
