How concerned should I be? My husband and I had a mishap with a condom last night and I took a plan b about 12 hours later. I have felt fine all day except for some anger, I'm on Prednisone and other meds due to a MS diagnosis, and anxiety. I have a history of ovarian cysts but also diverticulitis. But now I am having sharp stabbing pains in my lower left abdomen. It is coming and going, but when it comes it is a very intense pain that stops me in my tracks. I can't be on birth control, mirena, or anything like that because they cause things like ovarian cysts and extremes crampy in random times that cause me to end up in the fetal position.
Due to your conditions & medications, I'd ask a doctor or pharmacist for their opinion on the pain.
Plan B can certainly cause some cramping & pains, but due to the other things you have going on, I wouldn't be comfortable saying it's just Plan B.
Whether or not Plan B works for you, is another thing. It works by delaying your ovulation until the sperm leaves your body. If you're already ovulating then it can't do that. You'd need one of the other methods of emergency contraception.
Do you know if you were close to ovulation?
