Hi i have been having abdominal bloating and cramping some what on and off but mostly on the past week im tired and irritable all the time and yesterday i got a migrane. I have been getting a slight sore throat that only last like an hour the past two days. Me and my bf did have unprotected sex and he did go inside me on may 23 but about four days later i took the plan b pill also i was on my period from may 18 till the 21 then i bleed for two days two weeks after that period was over..i have tooken a pregnancy test and it came back negative..im just really wondering what is going on bc the stomach cramping and back cramping is dull but uncomfortable along with the bloating. If you could please tell me any possiblities that could be wrong i would really appricate it..it almost feels like gas but i really dont know also last night my colon was like throbbing in pain for like thirty mins i tired to take a bowl movement but nothing came out.

Hi there, Ideally Plan B should be taken within 72 hours after unprotected intercourse. In your case you took it 4 days later; which means plan B could be ineffective. However, if your menstrual cycles are usually regular, the chances of pregnancy is less if you had your periods from May 18-may 21 and intercourse on May 23. I am unable to understand what you meant by I bleed for 2 days 2 weeks after that period was over. It is quite possible that your periods must be nearing which might explain the headache and cramping, bloating sensation. I would advise you to Chat Doctor.  It will help with the digestion. A
