Hi,
Welcome to ehealthforum.
Swollen labia and bump could be attributed to pregnancy changes. The nail deformity can be due to anemia or essential nutrient deficiency. Discuss about these with your gynecologist/doctor. For the labial symptoms, you will require examination, blood pressure check, urine test done by your gynecologist/obstetrician to be able to come to exact diagnosis. Maintain high protein diet, drink plenty of water.
Take care.
