I may be jumping way out of line or.....

Just wishful thinking! me and SO have been having a ton of sex recently and the pass two days I've been extremely sick the smell of everything has me nauseous and I just feel sick, tired and almost weak the past two cycle have been pretty regular which is abnormal for me since I have PCOS but this month of February it was late and then when it came it was 2 days of very little spotting now I'm wondering if I should take a test or if I'm just absolutely out of my mind and there's no way I could be pregnant!
