My hcg level is 36 miu/ml. it was tested 11 days post iui. the nurse said its on the low side, and ill have to retest in a couple of days. this has me a bit worry for the time being. should i/shouldnt i be doing anything for this to stay viable?

After 11 days of IUI, your hCG level of 36 is not low, you should not worry much at all (hCG levels at 3 weeks: 5-50 mIU/ml). Stress and anxiety are not good for your pregnancy.

Any level of HCG post ovulation is a "positive" for pregnancy. at only "11 days" after IUI, "36" is not unusual. Your physician will repeat the HCG level again to show progression of the pregnancy. There is nothing one has to do at this point.
