I had <a href="https://glowing.com/glow-fertility-program">iui</a> done on the 16th with 3 mature follicles ready to fertilize, since 3dpiui I have been crampy and had lower back pain and I am now 6dpiui. It has lightened up a little bit goes on and off every now and then. Did anyone get a bfp at the end of the tww by experiencing "implantation" cramping or am I just crazy!!! Lol
