AM I PREGNANT???!!!!!

Hey ladies please help give me some info!!! My period is about 1.5-2 weeks away. For the past two days I have had cramps, constipation, and feel like my period is about to start anyday. I have had unprotected sex many times this month, with no clue when I ovulate. I have been taking a DIM supplement for almost a month now so my hormones will regulate out. Could it just be that?! Or does it definitely sound like I could be pregnant???!!!!! I have not experienced any spotting. It’s too early for me to take a pregnancy test. My breast were a lil sore today but nothing bad, and that has usually been a PMS symptom if I do. What does it sound like??! I also had lots of white/yellowish thick discharge for about 3-4 days.
