Am I, or am I not

Samantha
According to glow I ovulated last week, but I did some research and asked my friends and they said I don't ovulate till 10 days till af. Well we dtd last week (assuming I was fertile then) and have dtd so far every other day, including today. Lately I have been more tired than normal, and feeling a little bit nauseas. I'm not sure if I'm pregnant, or not we have been trying for a few months now. Any thoughts?
