Plan B symptoms, when do they start how long do they last?

I took Plan B 5-6 days ago. I had no immediate side effects. Starting yesterday my breast have become very tender and mild cramping. Today both have become worse. How long do these symptoms generally last? Os it common the symtoms take a few days to start. I am unsure what to expect, as this is my first time taking this. When I read up on it, most sites state only a few days right after it is taken. It was like the symptoms have been delayed in my case. I will also advise I was ovulating when my oops occurred.

I had unprotected sexual intercourse on Sunday and took the Plan B pill the same night- the next day I had really bad gas/stomach pains & super watery bowel movement. Tuesday & today the abdominal pain has subsided but the watery bowel movement is still here. I feel slightly nauseous & have no appetite. Could this be a side effect of plan B or is it possible I have food poisoning? My stomach was also hurting before I took the pill.
I've taken it once before & didn't have any side effects .

Hi Anon

It could be either scenario really. Did you eat unusual food? It could be side effects too since the body can react differently each time.

Hi Anon!

Thanks for reaching out to EmpowHER with your question!

Symptoms generally start about 3-7 days after taking emergency contraception - women are all different so symptoms will be different too. Symptoms generally last a week or less.
