We are sorry to hear of your situation. Usually the irregular bleeding that occurs during the adjustment period wanes after about three months. You may continue to experience longer/heavier periods, but the mid-cycle bleeding should calm down after the first 3+ months.
At this point, we recommend giving it another month to see if the situation resolves. You are not required to try to complete the
taharah process every few weeks if it is too stressful for you. However, be sure to speak to your husband to discuss the situation with him and share your feelings.
If the situation does not improve in the next month or so, please get back to us for further guidance as well as consult with your physician. He/she can check as to correct location of the IUD. You can also discuss whether short term hormonal manipulation (depending on the reason you cannot take hormonal birth control), or another medical approach, could be attempted to help resolve the situation.
B'Hatzlacha!
