Hi, i went to the nurse the other day and had a smear. While doing this i asked her to look for the strings of my marina coil and she could not see them. The doc had a look also and she could not find the device. I have to go for a scan today to see if they can find it and to see if i,m pregnant. Im very worried as I was not trying for a baby and have been drinking wine and have not been taking any folic acid. if it is the case i am will the baby be effected by this and will they remove the coil.

Hi, thanks for posting your concern in the Chat Doctor. Most commonly the IRENA string becomes invisible when it has hot displaced from its site of lodgment. Your doctor has correctly advised you to have a scan to find the exact location of the IRENA coil. And it should be considered as an emergency. So, scan should be done as early as possible. If it has got displaced or by any chance removed, there is chance that you may be pregnant. In that case chance of ectopic pregnancy is higher. An ultrasound scan can rule out that possibility. In case you become pregnant, and the fetus remains in the usual normal position, consumption of alcohol and no folic acid intake definitely poses risk of development of neural tube defect (NTD). Hence, if there is normal uterine pregnancy, and you want to continue with that, immediate commencement of Folic acid would be needed, and Anomaly scan should be done as per schedule. But, above all, the first thing you need is to locate the missed coil and hence please have the scan done at the earliest. In case you have any new query in the future, you can directly ask me questions @ http://www.ChatDoctor .com/doctors/ Chat Doctor.
