PCOS and false negatives

I'm 20. I was diagnosed with PCOS at 13. I have this intense gut feeling that I am pregnant. I'm having early pregnancy symptoms (occasional nausea, tender breasts, fatigue, and a couple others), none of which I have ever experienced during PMS. I've had two very light/painless periods and my HPTs have been negative, but I can't shake this deep feeling I have. And it's not that I'm psyching myself out because I want to be pregnant. I'm not TTC and I'm not at a point in my life where I would purposefully try for a child. I've read several articles published by OBGYNs that discuss PCOS and false negatives/periods during pregnancy. Has anyone else experienced this? 

**note** I would LOVE to see my doctor, but I recently lost my health insurance and won't have coverage again for about two weeks.
