I was 13 days late on my period yesterday. I started spotting and it stopped with in a couple hours at the most. That was yesterday. I have been getting nauseous for the last two or three weeks except yesterday. I have taken several pregnancy tests and all has came back negative. A couple days ago (Before the spotting) I did talk to a phone nurse at my gynecologist office. She told me to wait until next month and if I still didn t get it and got a negative pregnancy test to discuss with my gynecologist. I do have pcos but I have not had any symptoms with it since 2011. I have been getting regular periods since then. Could this be a possible pregnancy or could my pcos be acting up again?
