I went through the a whole gammet of infertility treatments, for anovulation. It was so stressful, and hard on my body. My periods were irregular 60-80 days apart. I started clomid and got pregnant and miscarried, and then after a couple of more cycles of clomid. I did the hormone injections (very expensive), coupled with interutero insemination. Got pregnant on the second round had another miscarriage. Was exhausted and miserable. My husband and I decided to take a vacation. Post pone further treatment and discuss it when we got back. Low and behold, I got pregnant.
Just tell your friend not to worry. The others were right the ovulation predictor kits are not that great. The sex everyother day method worked for a lot of couples I know. She should keep her appointment with her doctor (I needed to feel I was doing something). Your friend could be a very early ovulator or a very late ovulator in accordance to her period. So, the every other day thing could work great for her. Also, the more worked up she gets the harder it is to get pregnant. Believe me, I know that this is next to impossible to do, but she should try to focus on something else. Exercise, Yoga, art classes, a pet, vacation. Anything to take the focus off of getting pregnant.
If she is truly concerned and want to seek some expert advise. I would suggest contacting a reproductive endrocrinologist. I used Fertility Centers of Illinois. Dr. Lifchez. He was the kindest and best doctor I ever met. 2 of my friends went to him and had great results. The first steps of testing is to monitor your cycle and go into the office every other day for an internal ultra sound to see if your ovaries are producing and releasing eggs normally. Wait, actually the first step is to have the husband tested, then the cycle test, then Clomid, Possibly exploritory surgury to check if there is any blockage of the tubes or endometriosis, then IUI and or IVF.
Tell your friend to hang in there. I hope it happens for her soon.
