I am going to the doctors

I am going to the doctors next week when I am home but sadly I am in the middle of traveling. And I am wondering had anyone delt with this. So I should start with I did travel out of the us last week and did get bit by some mosquitos but I started feeling down hill the first day. We had been traveling in Florida and we arrived at the Bahamas I believe it was the first or second day and I stood up after lunch and almost passed out my husband had to grab me and I felt like the room was spinning. Okay we thought maybe dehydration anything but as the days continued dizziness and head rushes and nauseous continued. Now we are back in the states having the same issues and the headaches are accompanied by more fatigue and no appetite ( and I am a big foody) I have one more week of traveling and hoping it goes away. I am not sure if this is an illness rolling on. Hormones or what. I did only have a one day period during the time my period was due so not sure what’s going on
