I have a very regular cycle that my period always comes between 26-30 days. I usually experience symptoms like tender breasts, cramps and backache days before I have my period. I havent had a period that I didnt experience these symptoms all at once. Right now, it’s my 30th day and my period hasnt started yet. Also, the only symptom I am having is backache. I had sex on the 7th and 21st day of my cycle. I’m wondering if it’s possible that I am pregnant. Please help!!!
