Hi. I did iui on sunday and monday. Double iui. I had two mature follicles, and doctor advised us to keep contact till friday and after that only take medicines folic acid and progesterone. My first follicle ruptured on monday and second follicle ruptured on tuesday. Now im 4 dpo, im experiencing breast tenderness and sharp nipple pain and  severe back pain. Backpain persisting even after taking enough rest... Usually iui procedure doesn't cause any symptoms right? Or is it because of the corpus luteum?  Or are these pregnancy symptoms? I didnt start taking medicines then why am i getting these symptoms strongly? Please reply dear doctors.
