Hey. In some women pregnancy symptoms are similar to the flu symptoms so maybe you shouldn’t be drinking for the thanksgiving. Everything you have described resembles the same symptoms my sister had and after few weeks she has discovered that she is pregnant. So the best thing is to go to the nearest pharmacy and buy home pregnancy test. Even if that one turns negative and the symptoms still continue schedule appointment at your doctor’s office and consult with him. He will do a blood test and you will know for sure.
Did you consider what to do if you are pregnant? How does your boyfriend think about this? And if you didn’t want to stay pregnant why didn’t you use some kind of protection?
If you discover that you are not pregnant consult your doctor about contraception. There are various options so you can see with him what is the best solution for you.
