i had unprotected sex with my boyfriend and the condom broke but only a small amount of semen leaked out. the next day he bought the Plan B onestep and i took it around the same time we realized the condom broke a few weeks later i got my period and after that i took two pregnancy tests and both were negative and i thought everything was fine but then a sour liquid started coming from my breasts and I'm freaking out I'm not sure what to do
