The only difficult side of the IVF treatment is the daily injections you may have to take and the regular trans vaginal ultrasound scans they perform. But then thats nothing compared to the gains you get.The most painful part will be after they perform a small procedure to remove eggs from the ovaries. you will have to walk around like a old granny for two days because you will have pain in tummy if you stand straight. otherwise it will be like normal pregnancy till the end.
