OK, I know this is going to sound COMPLETELY ridiculous, but during my previous IUI and IVF treatments, I got mildly hyperstimulated and was in SOOOO much pain starting the day after trigger, and lasting about 5-7 days. I had the super painful bloating in my upper belly, as well as the cramps below. This time, I've got a little bit of bloating but nothing too painful, and some mild cramping and tenderness, but NOTHING like I experienced in times past.
