Had signs of AF coming(cramps, nauseous, mood swings etc.) Spotted once 2 days after my period was suppose to come and then nothing, still having AF symptoms, I took a test and it was negative. I Started bleeding on the 3rd-7th and it was clumpy and the color changed. I have headaches and I’m always tired. I am sexually active and use the pull out method. do i need to be worried? Is this worth going to the doctor?
