Okay, so I am 17. Ive only ever has sex once, but I don't count it for personal reasons. Anyway, this happened 4 months ago. But I've never had sex since then, and had all of my periods. One problem though. My last period, in may, was my last one, but I started having weird symptoms afterward. Cramping, nausea, increased appetite, food cravings, mood swings, extreme breast tenderness, constipation, and increased urination. There is no way I could be pregnant, but I am producing many signs of it. This started maybe a week after my period, and has not stopped.
What could it be, and what can I do?
