I just got back from a trip to Veradero, Cuba with my family. At night my parents would go to bed and me and my twin sister (Fraternal) would go out and party. On our second last night she hooked up with a guy named Chris, and I hooked up with a guy named Kyle- They're friends/roomates at the resort.

Well me and my sister have been starting to feel sick ever since we got back on Thursday. Julia made out with Chris, who was sharing cigars and drinks with Kyle. I also shared cigars and drinks with Chris AND Kyle and hooked up with kyle. Is there any way that we could have mono? Our symptoms are- Muscle pain, fatigue, loss of hunger, coughing, very bad abdominal pains. What are the symptoms? How long should we wait till we know for sure? Thanks
