Health Concerns

I know you guys aren’t doctors most likely and I’m planning on seeing mine but I just wanted your input as well. I’ve been having some concerning and weird symptoms and conditions and have been doing my own research online and it points to either pregnancy or some form of cancer (mostly ovarian), and other things could be wrong with me too, or maybe I’m just becoming fat and unhealthy. The symptoms I’ve been having are: rapid weight gain, abdominal pain, nausea, vomiting, not being hungry for a long time, sometimes feeling full fast, headaches, frequent urination, cramps, bloating, sore and larger breasts, fatigue, and indigestion (I think I mentioned everything). I haven’t had sex since October and I did take two pregnancy tests that both came back negative. What are your guys thoughts?
