You could get pregnant regardless of teh fact that you use protection, tho if you double protect, it is very rare but if you are, you ae the most fertile couple ever!;) Also, I had those symptoms when I was on the pill, which is why I came off of them so quicklly, The pill might just not be adjusting to your body as well as you would hope for, so if you have just started this pill talk to your doctor, if you have been using it for a while, talk to your doctor anyways. WHatever the problem is right now, it is best to seek medical attention:) good luck
