I had an <a href="https://glowing.com/glow-fertility-program">IUI</a> on 8/24. I am still experiencing some cramping. It’s not all the time. There’s been days when I don’t have any at all. The cramps come and go. They’re not super strong but still there. I’m not sure what implantation feels like and my test day is 9/7 and period should be here 9/9. I usually get cramping for period 1 week before it arrives. Can it still be implantation, is this normal or does that not happen at this point?
