I took 2 pregnancy tests after missing my period and I'm not pregnant. I read that if if you take Plan B 2 times in a month your period will be MIA for awhile. How long is that typically? I have not gotten it in 3 months and have noticed that my boobs have gotten huge and my stomach sticks out when it never used to. My diet has not changed since taking plan B so I'm wondering if I've gained weight in these two areas as a result of not getting my period in 3 months? Will I be back to normal once I finally get it?
