Okay - so I think I am getting ahead of myself - and everyone else. I just read over my last post and realized that if you are new to the world of IF you will have no idea what some of this
gibberish is. So here goes. The process of an
IUI starts out on the first day of your period - this is cycle day 1(or CD1). My protocol is to take 50mg of
clomid on CD5 - CD9. On CD 12 I am supposed to start testing for my
LH surge. What in the heck is an
LH surge you ask? Well, here is the long
explanation thanks to
ovulation-calculator.com:
At the beginning of the menstrual cycle, the body begins to produce follicle stimulating hormone (FSH). FSH facilitates the formation of a follicle on one of the ovaries. The follicle contains and nurtures the egg. When a follicle has adequately matured, a surge of Luteinizing Hormone (LH) causes the follicle to burst and release the egg into the fallopian tube - the moment of ovulation.
Throughout the menstrual cycle, a small amount of LH is produced - but during the middle of the cycle LH briefly and dramatically increases. Elevated quantities of luteinizing hormone facilitate ovulation - and OPKs detect this LH surge through anti-LH antibodies contained in the sensitive testing membrane of the test.
The LH surge is, alas, very brief - and in order to detect the LH surge, a woman needs to test at the right time of the month - and the right time of day. As LH is produced by the body in the morning, mid-afternoon is considered the ideal time to test.
Once the LH surge has been detected, successful fertilization is most likely to take place one to three days following the LH surge - with peak fertility at 36 hours post-LH surge. Since this ovulation "window" only opens once per month (and the unfertilized egg has a short 24-hour life-span) predicting ovulation accurately is very helpful when trying to become pregnant
So....
If i detect my
LH surge I will call the Dr's office the day I detect it and we go in the next day for the
IUI. Before the
IUI i get an ultrasound and they look to see how many follicles I have, how big they are (usually, a mature follicle is about 20 millimeters in diameter, or about the size of a small grape, just before it ruptures and releases its egg) and what my lining is measuring at (measuring the thickness of the uterine lining, known medically as the
endometrium, relates to determining how receptive it might be to the pending implantation of an embryo). If I do not detect my
LH surge by CD12 I will go in for an ultra sound to measure the size of my follicles. If they are big enough (18mm or larger) the Dr.'s office will give me a "trigger" shot. A trigger shot is an injection of the hormone human
chorionic gonadotropin (
HCG), which
actslike LH, can be given to stimulate final egg maturation and follicle rupture, releasing the egg. I should ovulate about 36 hours after the
HCG injection, which can be confirmed by further ultrasound
scans or an ultrasound for release. 24 to 36 hours after my trigger we go in for the
IUI.
So that's it in a nutshell. I don't know about you but my head hurts just thinking about it! Hope this helps!
