I Had Dengue From VI 2 Years Ago. I Have

I had dengue from VI 2 years ago. I have never felt the same since. I was back at work in the states before I even knew I had it, never treated for it or given a full chance to recover in a healthy manner. I found out this morning I am pregnant. I am also 40 with other high risk factors. Does the past dengue come into play? No one here fully understands the virus.
