I stopped taking yaz about 2 months ago. I had a normal period after ending yaz and had sex during that period (using condoms and pull out) I am sure the condom did not break or rip. I always had very irregular periods before birth control but it has been officially a month since I had sex and no period. I have taken 4 at home test and the 1 urine testat the doctor and they were all negative. But am still freaking out. Help! Any answers would be great.
