5 day late with a negative test?

According to this app I’m supposed to have started my period five (5) days ago and I haven’t yet. I have the early pregnancy symptoms like some small but wired eating habits, tiny faint cramps all around my lower abdomen, MISSING MY PERIOD, some foods that I eat I instantly have to go to the bathroom right after, I’ve even had frequent bloody noses almost one after another everyday or so, I’ve gained about 10-15lbs, about 3 weeks ago I was going to be drinking a lot and I started off with a mixed drink and I only had a few sips of it and my stomach started hurting soo sooo bad 🤢 it was twisting and turning but I didn’t puke.

UPDATE: I’m also having backaches, acne, bloating. I workout up to about 2 hours a day but some days it’s hard because my stomach doesn’t feel right, I get super dizzy when I try to workout hard, and right after working out I get extremely hungry, super tired, not to mention I’ve been more tired at night like I’ll normally fall asleep at 10pm, but now it’s at 5-7pm and I won’t wake up till 7-9am the next day.

UPDATE2: I’m now 6 days late and I’ve taken 3 clearblue pregnancy tests but they are coming up negative. I’m still having those symptoms but negatives on those tests AND still no period. What should I do?

I’m just so confused, I have some common symptoms and some not so common symptoms but a negative test??? Help.
