I've been craving orange juice, nauseated but better when I eat. Pressure on my hips and lower back. Haven't had a period since October and it is now April. What could this be. I have also been on a diet since January and only lost a little bit and can't lose no more I'm stuck at this weight.

Do you normally have infrequent periods? Have you spoken to your doctor about it? Could you be pregnant? If so, have you tried a pregnancy test? That would be the first thing to determine.

If you aren't pregnant, then it would be wise to see your doctor to determine why you haven't had a period in 6 months. It may be something as simple as a hormone imbalance. Depending on your age, it may be the start of menopause. Certainly testing would be necessary to find out for certain.

Yes time to see your doctor after 6 months.
