Patient's Query

Hello doctor,

I am a 22-year-old female. I had my periods on the 2nd of this month. I had unprotected sex on the 10th and took a tablet of Unwanted 72 within an hour of having sex. After five days of taking the tablet, I experienced spotting for two days and very light bleeding on the third day. I have not had my periods since then. What are my chances of getting pregnant? If I am not pregnant, when should I expect my periods? Should I count my cycle from 2nd or 15th, that is, the date when I experienced light bleeding due to pill? Also, could the bleeding that I experienced be implantation bleeding since it was too less? I also took a home pregnancy test on 21st that gave a negative result but I am not sure if I can rely on it. Should I take another pregnancy test?

Answered by Dr. Sameer Kumar

Hello,

Welcome to icliniq.com.

The Unwanted 72 has a success rate of 99 %, so the withdrawal bleed that you experienced on the 15th is more likely to be a pill withdrawal rather than an implantation bleed. Another reason being you were on day 9 of your cycle during your act of sexual intimacy which was within your safe period, presuming that you have regular cycles. However, you may get a serum beta hCG test done to rule out pregnancy if in doubt conclusively. If the hCG levels are less than 3 mIU, then you are surely not pregnant.

If not pregnant, then your next menses shall be by 20 to 21st of the following month or late by a week to 10 days considering the 15th as your fresh LMP. There can be a delay of seven to 10 days, as it is a known side effect of Unwanted-72 and can be seen for one to two cycles.

Regards.

Patient's Query

Hello doctor,

Thank you for your help.

I had an ultrasound on 17th. My ET was 0.23 inches then. Does this rule out pregnancy? What are the conditions under which Unwanted 72 can fail?

Answered by Dr. Sameer Kumar

Hello,

Welcome back to icliniq.com.

An ET (endometrial thickness) of 0.23 inches rules out pregnancy on 17th. There are no set conditions as such which are documented but 1 % chances do exist of its failure.

Same symptoms don't mean you have the same problem. Consult a doctor now!
