Haven't been taking pills on time or everyday. had unprotected sex but he pulled out. 6days later have nausea headaches no appetite bloating everyday?

Unlikely: It's unlikely that you're pregnant but i would take a test in a few days. It's ideal that you take the pills at the same time every day, but a few hours difference shouldn't increase risk for pregnancy all that much, unless you are on the Progesterone only mini-pill. You can get an app on your phone that will remind you at the same time every day!
