Hormones?

In January I switched birth control from the mirena iud to the patch, when I did, we didn't wait the month before having unprotected sex. Now, I have been having a lot of wierd symptoms like increase in breast size/ sensitivity, heightened sex drive, extemely hightened sense of smell, a little nausea and lack of appetite. I have been getting my period, the last one eding on April 5th so I have been writing all this off as fluctuating hormones from switching BC, but I am now waking up in the middle of the night craving beef Ramen noodles... the only time I have ever ate the beef flavored Ramen noodles was during the first trimester of my pregnancy with my son... so I'm kinda freaking out now lol and it doesn't help that all my coworkers keep asking me if I'm pregnant! I guess I could just use some good advice from someone who isn't biased on whether I should or shouldnt get pregnant!
