Period is a week late

Usually my period last 4 days. 2 weeks after the start of my period is when I typically ovulate, and then another 2 weeks later my period starts again. Sometimes my period is off by a day or two, but other than that it’s pretty regular and has been for years. I also usually have no PMS symptoms other than acne right before my period starts and that’s how I know it’s getting ready to start. I could’ve swore I was pregnant because my boobs have been super sore and I’ve been feeling nauseous in the mornings, but haven’t thrown up. Nothing has happened that I can think of that would throw my period off by this much. I did have unprotected sex a lot during this cycle, we aren’t trying to get pregnant but we aren’t really avoiding it either lol. I’ve taken 3 pregnancy test. One on the day of my missed period, one yesterday, and one this morning as soon as I woke up. They’re all negative but still no signs of my period. I figured being a week late enough hormones would be build up to get a positive? I’m not convinced I’m not pregnant until my period comes lol. I’m considering calling my doctor but I don’t know if I should wait a couple more weeks or see if I get a positive test first? Any advice would be greatly appreciated!
