I stopped using the Nuvaring in February, as my then husband and I had decided to try to have a baby. After I stopped taking the birth control I didnt have a period for 3 months. In May, I had a normal period, then didnt have my period for 2 motre months. In August and September I had 2 irregular perios, that were light, and were very dark brown blood. Ever since September, I've had no period again....but am experiencing very bad cramping a few times a month. This cramping also comes along with a feeling is dizziness, and what feels like a hot flash. I am only 23 years old, and am not sure what exactly is going on...Any suggestions?
