Patient's Query

Hi doctor,

I am a 32-year-old and have missed periods. I tried the pregnancy test, and the first T line appeared darker and suddenly disappeared, and only the C line exists. Please tell me if I am pregnant or not.

Thank you.

Hi,

Welcome to icliniq.com.

I understand your concern.

I hope that this answer finds you well. I understand that you missed your period for 36 days and used a pregnancy test kit. Usually, the presence of two lines means pregnancy, while the absence of a control line (C) indicates the test has failed. In this case, make a new test, follow the instructions correctly, and take a picture of it after the time written on the package passes. Then request a follow-up and share a photo of your test.

I hope this information will help.

Thanks.
