I got my iui done on 20th Jul, I did a upt at home today morning but results were negative. my periods are late by 2 days now. I was given the progesterone tablet(vaginal) for 15 days and now that's completed as well. Had some mild back ache and leg ache for 2-3 nights for few minutes 2 days back. Is it too early too for the detection of hcg in urine? Should I wait for another week? Any suggestions would help.
