Okay , Ive recently was on my menstrual cycle and I am experiencing unexplained symptoms the day after I came off my period. Symptoms such as low abdominal pain, gas, fatigue, lower back pain, and my stomach feels hard. Ive excecised extreme the day before my period was due , if that has anything to do with it. My body is very sore due to the excercising. I also had sex while ovulating. My partner and I had used a condom the first time, but the last two times was unprotected but he didnt ejaculateCould I possibly be pregnant? Or is it something else?
