<s>[INST] I had two four cell embryos transferred on day two which was four days ago. I have woken up very hungry each day since. Is this a sign of anything? I don t seem to feel different in any way. The embryos are from my partner who is 35, I am 38. She had 8 eggs collected we kept four and shared four with an anonymous recipient. Three of the four we kept were good for icsi but only two fertilised, these are the two i now have. Should I feel anything? [/INST] Hello there,I can understand your concern. The symptoms you are having of hunger do not suggest anything in particular. One may not feel any different after an embryo transfer. It will take about 2 weeks before a pregnancy test can confirm whether your embryos have stuck to the uterus lining. Till then wait and be calm. You cannot do much and you may not feel anything at all. Some women feel mild pulling pain in the lower abdomen but these are all non specific. So dont worry and relax. Wait for the pregnancy test and till then take the medicines that your treating gynaecologist has suggested. Hope this helps.All the best and take care. </s>
