Anyone else have this problem? My backs been aching on and off for the last three days. Also I've been vomiting (ew) for the last three days. Basically haven't kept anything but tea down. I was trying to monitor weight gain since I have heard u can gain a lot as u stim and I've actually lost a pound and a half! I told my dr about the nausea today and he said I must have a bug or maybe it's from my metformin cuz it shouldn't be from the shots (im on menopur and gonal f) everything seems fine otherwise, no bloating yet but I think he counted 17 follicles and said I'm responding great. This will be day 5 of stims tonight. Anyone else have these issues? Ugh I hope it doesn't get worse!
