Health Issues During Pregnancy

I am facing some health issues right now. There is an enlarged lymph node on my neck and it just came out suddenly. I had a cold and headache few weeks ago. After that, the lymph node became big. I had a biopsy Friday because my doctor said they had to examine it as soon as possible. They want to know what causes the enlargement so they can suggest a treatment since I am pregnant.

The biopsy result takes two weeks so I might receive a feedback by Friday or Monday of next week. I am praying that this is not very complicated.
