I injected once a day and had an bt every second day to monitor my estrogen level. I also had u/s to monitor the follies and make sure that I wasn't over-stimulated. I started on 50 but it wasn't doing anything so went up to 75 on CD15. Evenutally on CD28 my estrogen was high and I had 2 nice follies so we did IUI. We were fortunate enough that we conceived first cycle on FSH/IUI. The injections themselves don't take much time but constantly going to the clinic for bt and u/s does..............but if it gets you what you want then it is worth it!
