Hi Nogoes,
I've done some replies for you as seen below:-
You write:-
"I did mention the possibility of an hormonal imbalance to my GP but she said she would not refer me until January because I have always had an irregular cycle and conceived ds very quickly".
January next year!!!. Do not accept this, infact I would see another doc and ask that you are referred or at the very least to have a blood test done. If you have always had an irregular cycle this is even more reason to refer you sooner rather than later. This person is also wrong to assume that because you conceived your firstborn quickly you won't have any problems second time around.
"She suggested ovulation tests because she said that they would show when I was ovulating so I would know when to actively ttc".
Again this is ignorance on the part of the doctor. Some of them are pretty much ignorant when it comes to such matters. Doing blood tests would be far more useful to you than doing opk's; a blood test would give an accurate picture as to what your hormone levels are like.
"I am a little ignorant about these matters so not really sure what to do, what are LH levels? If the test shows that I am ovulating does that not mean that it is my most fertile time?"
LH (luteinising hormone) works in conjunction with FSH (follicle stimulation hormone) early on during your cycle. These two therefore are very important hormones, they play a huge part in ovulation happening or not. Normally these two levels are the same; if they are not then ovulation is affected.
OPK's work on two misleading principles; namely that women only have one rise in LH every month and that such a rise is immediately followed by ovulation. Both of these statements are simply not true.
Irregular periods are often caused by hormonal imbalances; the cause of this needs to be properly determined and doing opk's won't address this at all.
HTH, do not be fobbed off!!!
Any other questions just ask
