Hello ladies just wanted to know if anyone has any wisdom on this topic as I have had so many conflicting answers from professionals. I take mefanamic acid for painfull periods prescribed by my GP. In the leaflet it states that it can cause fertility problems if ttc. I have spoken with my pharmacist and nurse practitioner and these both stated that this is only if you are taking it regularly for other inflammatory pain. They suggested taking it only when I need to during the first few days of my cycle will not effect my chances. Google is my enemy and friend and I have looked this up and nothing I have read can give me a definitive answer. All suggest that taking it regularly can impact on your chances as can ibuprofen etc.. and all should not be taken in pregnancy. Thanks in advance having a really bad crampy period and am in agony.
