So I have PCOS & irregular cycles. I have been TTC w/ my SO for nearly 3 years with no luck. My last period was Oct. 30th - Sept. 5th. The day my period stopped, my boyfriend & I had unprotected sex throughout the week. I noticed that I had increased CM also. Now I am having cramps in my left ovary & I wanted to know if any other girls with PCOS had sharp cramps when they had implantation.
