Patient's Query

Hello doctor,

The last time I had unprotected genital contact was four months ago, right after my period ended. It occurred eight days apart from ovulation. It was not actual intercourse as there was no penetration or ejaculation inside my vagina, and I am a virgin. However, I took the emergency contraceptive pill (ECP) within 12 hours as directed. Subsequently, I experienced withdrawal bleeding from the pill and had my periods in the following two months, both of which were on time. I also conducted six negative pregnancy tests, and one month ago, I underwent an ultrasound at the hospital. My gynecologist confirmed that my uterus is completely empty, and everything appears to be perfectly normal. However, my period is two days late. I am unsure if this is usual for me as I did not track my period before all of this happened. Doctor, could I still be pregnant despite the details I have provided? Should I repeat the ultrasound test in a few weeks? I would greatly appreciate your precise answer.

Thank you.


Welcome to icliniq, and thank you for choosing us as your provider for health care.

I have gone through your history and understand your concerns. There is not any chance of pregnancy in your case. The emergency contraception pill is very effective, and moreover, you had an ultrasound (attachment removed to protect the patient’s identity) that did not show any gestation. Also, these are high-dose progesterone pills, so the cycle gets affected. Usually, periods get delayed after abrupt withdrawal bleeding. So, it is better to take a regular birth control pill from day five of your periods for 21 days, and then your periods will come, and you can start a fresh packet. This regularizes periods as well as offers good contraception. I am happy to help you and will always be available whenever you need me at icliniq.com.

Thank you.
