Early Signs?

Trista

So I got my Skyla removed on 1/9 and started taking the pill on 1/11. I feel very sick and did have unprotected sex on 1/10 as well as a couple times after starting the pill. I feel very bloated and nauseous. I have been sleeping much longer than usual. Is it possible that I am already having early signs of pregnancy or am I having a reaction to taking out the IUD and starting BC pill?
