Suggest Cure For Nausea, Headache And Missed Menstruation

Symptoms for 3+ months - Constantly lower abdominal pain - Sharp shooting pains either side - No period for over 18+ months despite no contraception (only condoms) - Pain after sex & sometimes during - Bad bloating, to the point I look pregnant - Nausea - Sore achy boobs - Headaches Last week I was told I had a water infection which could of led to some of the symptoms. I was put on a week course of Nitrofurantoin. I was told to go back to talk more once I had finished the anti-biotics. Today I went to my GP to discuss these problems, the infection has cleared up & my urine shown no trace of it in my system. She was concerned as all the symptoms are still there. She put in a referral to see a gynochologist at my local hospital however I have been told I won’t get an appointment for a few months. Several NEGATIVE pregnancy tests (in-store & at GP) Very worried & concerned.
