i have no way of answering that question based on the information you have posted. if you are trying to get pregnant i suggest that you consult your medical provider -- someone who knows your medical history and someone who is able to examine you (and your husband). your thyroid may have nothing to do with your inability to conceive or have regular menstrual cycles.
