My period was a week late so took a clear blue digital test, after spending ages in boots trying to decide the best one to buy. I am not planning on getting pregnant so was delighted when result was negative. BUT 2 days later still no period and am feeling definitely different. Am tired all the time, have cramps in my lower abdomen that I keep telling myself is my period coming on but it feels different. Can't drink alcohol, it makes me sick and am starving all the time. Should I do another test? has anyone else had a similar experience? What tests would you recommend? any advice is very much appreciated xx
