I am 50 years old and, according to my labs, am post menopausal. I had sex on May 26. By the first week in June, I was extremely dizzy and nauseous and was urinating more frequently. I went to the doctor thinking that I had just gotten water in my ears in the pool and possibly had a urinary tract infection. The answer was no to both. The next symptoms were pelvic cramps, vaginal cramps, low grade fever, metallic taste in my mouth, sneezing and one episode of mucousy discharge. My two dogs have also been fighting a lot.......like they're trying to protect me. I did two home pregnancy tests ( probably too early) and had a urine pregnancy test at the doctor's office (7 weeks after intercourse). All were negative. I feel pregnant.....what else could it be? I have also gained about five pounds and feel bloated.
