What is going on with me?

This is my 3rd test I've taken and it looks negative. I'm around 25 days late and I'm on birth control so idk what's going on. I did switch to a slightly higher dose of bc two packs ago but other than it being more estrogen it's the same formula so I didn't think it would have this much of an affect? I'm on the last week of active pills before my placebos but I still haven't gotten my period from the last pack! Any advice/help would be appreciated.

Side note- my boobs have been feeling a little bit tender which usually happens before my period so maybe it was just skipping a month and I'll get it next week?
