So 2/6- 2/9 I had my period. 2/15 I had unprotected ejaculatory sex and took plan b 2/16 about 24 hrs later... we had sex again but he came inside of me again not understanding how the pill is supposed to be taken..(don't feel like typing out the whole scenario so don't come at me sideways.) Not sure when I ovulated but I started spotting 2/23 and here it is almost 3 weeks later of light bleeding where i need a panty liner at most. I've had on and off cramping and the day before yesterday I experienced some pretty bad back cramps and pelvic cramps on my left side. Today the cramps are mild and i only see pinkish blood when i wipe. Should I be concerned? No we don't take plan b on a regular basis and im aware of the side effects. I am not on birth control and we typically pull out. When should I test?
