Instagram won't let me post?

When i press the middle button where you usually upload videos or photos, it stretches out my entire iphone screen to the point i can't see my battery percentage, my time, etc. I have to wait over 5 hours just to post a few more photos and then the whole process is repeated. I don't know how this happened, it was out of no where. I already uninstall and reinstall and restarted the app, but it doesn't **** anything!
