emergency contraception
"This is the second time I took Plan b, and let me tell you....it is effective but messes up your hormones and ph . I took plan b 3 weeks ago oct 16.. 5 days later i got what i thought was my period , that lasted for 17 days. Bleeding for 17 days was a nightmare. the first time I took plan b i got my period 5 days later and then again every 2 weeks for 2 months followed by a yeast infection. Now I think my period is over finally after 17 days i am spotting very lightly with yet another yeast infection. never once in my life have i had a yeast infection except for after taking plan b. I personally will never take it again  ."
