My cycle lasts between 30-33 days, my period is about three days average. This month, I thought I had a yeast infection but it went away. I could feel pain in my ovaries starting two weeks after the first day of my period and it hasn't gone away. I just started bleeding on time, but it was brown, not heavy. I've had dizziness, nausea, bee tired, have tention headaches, not really cramping, some lower back pain, been overly emotional, breast tender, weight loss (about 5lbs), sweating but cold, sore throats. I feel like I have the flu, but no one I know does. Could this all be PMS? Or a possible pregnancy?
