i am just wandering if any one that has been through IVF can help me? Would like to know how long the ivf drugs stay in your system for, we started our injections back in Nov and had a BFN in Dec sad But lately I have been feeling very fatigue by late arvo and having no energy and feeling hungry all the time, could it be possible than one of dp sperm has got through due to the amount of extra hormones from the ivf drugs?????
