A lot of "What if"

I had the 3 year Implanon for almost 5 years and just recently had it removed. (I loved it!) I was on my period when I got it removed, since I keep my <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> up to date, I am currently ovulating. However, for the past week I have been waking up so nauseated, extremely hot and tired. My husband and i have sex about 4 times a week but this week it has been more, when I ovulate I am SUPER horny. Also, only salty foods help a lot with the nausea. I haven't taken pregnancy test because payday is not here yet. What are the chances that I am pregnant right after taking my birth control out?
