HI, thanks for using Chat Doctor The efficacy of IRENA as a contraceptive is between 99.3% to 99.8%. This only leaves a small window for pregnancy to occur. Even though the risk is very small, you can consider a pregnancy test to rule out the possibility of pregnancy. The symptoms can also be related to the period symptoms that you experienced. I hope this helps
