Hi guys. I’m late by 7 days.. I basically missed my whole period. I never have been late, I’ve always been on time with my menstrual cycles. I’ve took 3 pregnancies test and the results were all negative. Was it too early to take the test? Or should I get a blood test? I’m nauseous from time to time, body is sore, many headaches, very tired, big appetite, and breasts are very sore. Should I be worried?
