First IUI I did not. It failed. Second IUI I figured it would take if it was supposed to and returned to my normal routine. That one stuck. Just my 2 cents.

I continued my running routine as per usual after my IUIs. I will note, however, that I only ever had a max of 3 follicles.

I was told moderate exercise was okay to do.
Avoid weights.

The main reason to refrain from exercise is a risk of harm to your ovaries, not because of interfering with potential pregnancy. With IUI, there shouldn't be a problem, since you weren't all that stimulated.

I just had an IUI Monday morning. I was planning on working out tonight, but wasn't sure if I should take another day of rest. I know my RE would tell me to just go ahead and get in a workout if I want. But. I'm hesitant to knock anything around...What do you do?
