Am I pregnant, I have a late period but few symptoms?

Patient: It has been 41 days since I last started my period, which lasted about 5-6 days. I stopped taking the pill just before that and had taken 2 months with no break before that. The last time I had sex was about 5 days before my last period and was having sex every day 3 weeks before that. I have also been feeling gasy, find it hard to lie on my stomach for a long time like there is something that i’m lying on and my stomach makes a lot of noises. Last but not least I have been really emotional for about 2 weeks, other than that I have no pregnancy symthoms. Could it still be possible that I am pregnant or am I late due to something else?

Symptoms: stomach ache, gas, late period, headache, stress
