Mandi is right. It's not just illegal to be pregnant and unmarried, it is illegal to have sex with someone who is not your spouse--pregnancy would be proof that you did just that.

In the case of any dispute the man's testimony is given twice the weight of a woman's and as we discovered recently, a woman was convicted of illicit relations with a man while that same man was acquitted of illicit relations with that same woman. However, if you are pregnant, you will probably get a suspended sentence followed by deportation. Take Mandi's advice to be careful and you should probably call your embassy.
