My cycle is 28 days. In June it started on the 27 it was a normal cycle (4ever days). I had unprotected sex on July 11, I didn't know that I was fertile. My cycle came normally 11 days later. On August 19 I started spotting, I didn't need pads or tampons so I used panty liners. My cycle was due September 14 but came late on the 18 and lasted about 2 1/2 days. I've had a horrible headache, gas, bloating, nose bleeds, frequent urinating, lower back pain, stomach pain, lack of sleep, fatigue, hair on my face and breasts, a little acne, and heartburn. I've had nausea, but no vomiting. Of course the first thing I thought was pregnancy, but I've taken 2 tests and both were negative. So can someone tell me if I'm not pregnant then what's wrong?

There's absolutely no way for us to give you a diagnosis online. Not even a doctor can do that.

The symptoms you're describing could be many things. You'll have to see your doctor for a diagnosis.

Ok, thank you.
I will make an appointment as soon as possible.

The other of course, just wait a month, see if you get the next period. Some women have a lighter period, on the first one, but it will not have one, on next.

Also when you test, Are you doing it first thing in the morning as soon as you wake up, that gives the best test
