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 is a symptoms complex that women experience few days before their expected periods.
The symptoms includes
Swollen or tender breast
Upset stomach, cramps or bloating
The second possibility is of side effects of positioned 2, which include:
, nausea and vomiting,
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
