Hello, I am 29 years old and was diagnosed with PCOS 4 months ago. I am on my third round of Clomid. The first two rounds, I experienced almost no side effects - just a little dizziness. this round, I have experienced breast tenderness, nausea, extreme vaginal discharge, heartburn, and extreme mood swings. I am now 4 days late for my period and the hpt I took 2 days ago came back negative. I am going to take a blood test in 2 days. Today I woke up with light cramping, but I never started my period. (my cramping is always very heavy and I start bleeding almost immediately). Could I be pregnant? If not, why am I just now experiencing these symptoms??
