Hi thanks for your question
Your last menstrual period was on 1st of October
You took emergency
contraception within 6 hours of unprotected sex on October 17th
Your due date was 29th of October.
Chances of your becoming pregnant are very less.
The symptoms you have described seems to be of
premenstrual syndrome (PMS)
PMS is a symptoms complex that women experience few days before their expected periods.
The symptoms includes
Swollen or tender breast
Feeling tired,
Upset stomach, cramps or bloating
Constipation or diarrhea,
Back pain.
The second possibility is of side effects of positioned 2, which include:
Stomach upset, nausea and vomiting,
Abdominal cramps
Bleeding disturbances
You may have your normal periods within 1 to 2 days.
If you didn’t get your periods in another 2 days.
Wait for a week, and then go for
pregnancy test to determine whether you’re pregnant or not
Further management depends upon the result of pregnancy test
Hope I answered your question
