So I had my first IUI 8 days ago on my second clomid cycle and also took the trigger shot 9 days ago. I noticed that I had cramping the day after the IUI and that continued ever since. I started endometrin on Saturday and the cramps have continued on and off...I don't remember having cramps the last time I took endometrin back in August but I know you can have them as a side effect. Anyone else have cramps throught after ovulation? I am not due to test until Monday but I'll most likely cave and test on Sunday morning.
