I do have fibromyalgia and your symptoms of constantly hurting all over, fatigue, history of migraines, anxiety and insomnia are all some of the symptoms I have as well. When there is a family history of fibromyalgia you are more apt to develop it. Pregnancy can exacerbate symptoms and some women actually believe their pregnancy caused their fibromyalgia. A recently published study reports that women with fibromyalgia will experience worsening of their symptoms during pregnancy. Yes, you can be diagnosed while pregnant and studies have also shown that more women are diagnosed with fibromyalgia when they are pregnant.

I would strongly suggest that you inform your doctor of your symptoms and the fact that they have worsened. Now would be a good time to find out if you indeed have it, although you will be limited in the medications you can take while pregnant. But since medications are trial and error you can focus on that once your baby is born. Also look online for exercises for fibromyalgia while pregnant, but talk to your doctor before doing them.
