Had my ET today and due to start Heparin. Also been prescribed Antibiotics (doxycycline)by the IVF hosp which is standard procedure. My dilemma is that the paperwork for the antibiotics says one should tell the Dr if taking this medication with Heparin or any other blood thinners. Could not ask the hospital however as they do not believe in the whole immunology thing. Just wondering if anyone else has been in this situation and what they have done.<P>Thanks in advance for taking the time to read and answer.<P>Kiki
