Are these symptoms in early pregnancy?

My DH and I have been ttc #1 for over a year. I am two days late for Af with negative pregnancy test. I have had some sharp pains in my stomach over the last few days, they come and go. Sorry if tmi but it kind of feels like gas pockets. The flu bug has been going around so I figure that might be what's going on. I have lots of other symptoms but not sure if they are just in my head, since i've never been pregnant before. Please let me know if having the feeling of "stomach bug" or sharp pains were a symptom for you and how long after your period was due, did you get your bfp? thanks so much :)
