Not sure what to think 😐

Okay so my last period was May 3 and I was suppose to get it may 28 but I'm 10 days late now and I do take birth control but for the past couple months I've missed quite a few cause of my time frame and for my pill pack this week is my sugar pills and still no period  (btw haven't found a good timing for it since I just graduated and everything is different now) me and my boyfriend do have unprotected and I had posted before and got told to take a test so I did and it was negative but I only took one and I've had the worst insomnia,I'm very moody, and just tired all day and I feel like I'm eating a lot I'm just not sure why I haven't got it. Any type of ideas would be really helpful
