What does bleeding indicate after taking Unwanted 72?

Question

Hi doctor,

I have been using birth control pill (Crisanta LS) from last 2.5 years.This month I started on 13, and I doubt I missed 1 or 2. After 13 days of starting the pill, had safe sex with a condom, but we doubt that it broke. To be safe, I took two doses of Unwanted 72 the next day and stopped regular birth control. After eight days, I got bleeding, and it lasted for five days (same number of days as my regular period after stopping pills every month). What was that bleeding? Was that my normal bleeding or withdrawal? I am confused as this was near to expected period. Then, I did HPT, and it came to be negative. What are my chances of pregnancy? Does this bleeding confirm that I am not pregnant?

Somebody suggested that I can start my regular birth control pills and I started. After 10 days, I got my full abdomen ultrasound done. It indicates that no focal lesion was seen and endometrial thickness is 4 mm. Uterus size is 88 mm - 43 mm - 42 mm. Do the thickness and report confirm that I am not pregnant? What is the normal thickness at this stage if I am pregnant? Also, the doctor suggested me to stop birth control pill until I get my regular period. Is that correct? When should I expect my next period? As I had regular birth control pill for 10 days, will it affect my next period?

Hello,

Welcome to icliniq.com.

What you experienced was a withdrawal bleed following Unwanted 72 (emergency contraceptive pill), which occurs in 7 to 10 days post emergency pill intake. So, it is normal. There is no pregnancy at all, as is confirmed in the ultrasound pelvis with ET being 4 mm. ET would have been more than 16 mm with decidual reaction if you had been pregnant. Latest bleeding becomes your LMP now (last menstrual period). If you have stopped the birth control pills now after taking them for 10 days, then there is a likelihood that you may experience some spotting within a week and if you do not continue the pills further, then your next menses shall be delayed by over 10 days as a known side effect of Unwanted 72. You should practice barrier contraception in that case to avoid pregnancy. But, you can be assured that you are not pregnant.
