Welcome to the ehealthforum. I am glad to help you out.
Your concern is regarding the lymph node in the groin. Pregnancy per se doesnât cause an enlargement of the lymph nodes. Lymphadenopathy (swollen lymph nodes) is usually caused by a viral or bacterial infection. Other causes include allergic reactions, arthritis, cancer, and an overactive thyroid (hyperthyroidism).
I suggest you to get this lump examined from a physician and get a fine needle aspiration cytology done to confirm the diagnosis.
It is very difficult to precisely confirm a diagnosis without examination and investigations, and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
