Anyone else experience personally unusual bc symptoms?

I've been on the pill for 2 years as of right now. I've always taken it at 6am because it was the only sure time I wasn't busy and would be able to take it (this was during high school and i was very active in school where my day would go from 6:30am- almost 10pm with no breaks in the middle so 6 was really my only time to take it). I've never experienced the nausea side effect since I first started, but the new pack I started this Sunday that I'm currently on, I decided to take at 8:30 pm because since I've graduated, i really have no reason to be up so early. since starting this pack, I've been waking up the morning after taking the pill feeling very nauseous and dizzy. I haven't been sexually active in almost 2 months and even with my pill we still use condoms. I'm going to change the time back to morning, just not as early as I had it before. I'm wondering if anyone else has experienced side effects of birth control they hadn't previously experienced after changing the time of taking the pill?
