Understanding Low FSH Levels & Fertility - What to Do Next

Question
Hello,
We have been ttc for 5 months now (went off BCP in May).  I was in for a papsmear last week and mention to my doctor that we are ttc and my cycles are still very irregular.  He did a preliminary blood work-up and called to say my FSH level is very low.  He had me take a home pregnancy test and it was negative.  I did have my period 2 weeks ago, my temps dropped on the first day of my cycle.  I certainly don't feel pregnant.  I took another HPT this morning, and again it's a negative.  The doctor took new blood yesterday to repeat the first test and do a pregnancy test ( I really don't think I am pregnant).  What would cause "very low FSH"?  I had 2 children in the late 1980s, so it wasn't a problem then, of course I am 15 years older now (I am 33).  Is there anything they can do to "fix" the fsh level?  I trust in my doctor completely to help figure this out and correct it, however I am trying to go into this as informed as possible.  I thank you for taking the time to help!

Answer
A lower than normal FSH level may indicate a problem in your pituitary gland. It does not indicate any problems in your ovary. It may merely have been a time in your cycle when the production of FSH was at a low point and, on repeating the test, it may show normal values. If you have regular cycles (28 days apart), you probably ovulate around cycle day #14. YOu can only become pregnant if you have sex on cycle day #13, 14, 15, or 16 each month. Concentrate on having sex around those days. YOu can further pinpoint the exact day of ovulation if you purchase an ovulation predictor kit from the pharmacy and check your urine around the suspected time of ovulation. Just keep trying and you should conceive. Good Luck to you. The best time to take a pregnancy test is seven days after you miss your period. Earlier than that is not accurate.
