I had the paraguard placed on june 24th, and had a normal cycle starting july 25th, but not no cycle for august. (-)hcg home test today. problem?

May be normal: Since you have paraguard placed ,the chances to get pregnant are unlikely . Your period is delayed by 4-5 days only which could happen normally .Hope you will get your period in next 2-3 days and you get relived .

Maybe: One of the many side effects for an IUD include irregular periods. It is also possible to become pregnant with this apparatus. I think that its time for a sit down with your doctor so he can explain all of the possibilities. Good luck
