So terrified

While showering I recently found 4 lumps on the inside of my labia. It took me five weeks to get an appointment with a lady GP but when I finally saw her I was so shocked. She said that it was a worse case scenario but they could be genital warts and I may have to go to the GUM clinic. I am so confused. I have been married for 20 years (second marriage) and have NEVER even thought of straying. My husband (who I totally trust) says he has not strayed. I have to go back to the GP this week where another GP will also "take a look" . I cannot even start to explain how totally confused and scared I am. Has anyone else experienced any "peculiar" lumps and bumps in this area and what did they turn out to be? I'm absolutely terrified.
