Hello, and I hope I can help you today.
If you got a period after unprotected encounter, and took emergency
contraception, you are not pregnant. Furthermore, the hormones in the emergency
contraceptive made your period shorter this month, which is another sign that the medication worked successfully.
Many of the side effects of the morning after pill can also mimic
pregnancy symptoms. So it is not unusual to have
bloating, breast tenderness, and other symptoms women commonly associate with pregnancy.
"
Implantation bleeding" is actually a medical myth. 15 percent of women bleed during early pregnancy, and if the bleeding occurs before you actually miss your real period, people assume it is due to implantation. But most women do not bleed at all from the moment they conceive, and missing their period is the first sign of pregnancy.
So you do not need to worry about pregnancy as you have all the signs that you got a period and did not conceive.
I hope I was able to adequately answer your question today, and that my advice was helpful.
Best wishes,
Dr. Brown
