It took us more than 2 years to get pregnant with DS #1. We were doing fertility treatments and were on our last cycle of IUIs with a combo of clomid and injectable meds triggering ovulation based on when ultrasound showed it was time and timing the IUIs accordingly. The next cycle we were to move on to IVF. That cycle for some reason the follicles were slow to grow and we ended up realizing I wouldn't be ready to ovulate before DH and I left to go on a cruise we had been planning for some time. We debated rescheduling but decided we needed a break so we went anyway. I was uncomfortable as I had something like 5 follicles competing to get big enough to be the ones to get big enough fast enough to ovulate with the RE predicting 3 would be ready about the same time. I felt like I had boulders in my stomach! Not much happened in our cabin at night because I was so uncomfy. When we got home we went to the REs office and they confirmed I had ovulated and based on the size of the corpus leutum cyst on my ovary (the sac the egg ruptures from basically) and hormone levels they knew about how many days before I had ovulated. I was sure there was no way I was pregnant because (1) we'd been trying for 2 years (2) DH had been in the jaccuzi several times...which according to everyone should have killed off most of his swimmers (and increased the chance for a girl) and (3) the timing of when anything DID happen and when I ovulated (confirmed by dating the pregnancy with early ultrasound) was too far between the 2. So by all of that when I ended up pregnant, we were SURE it would be a girl. NOPE. All boy.
We're talking DH in the jaccuzi every day and timing 4 days pre-ovulation. By the Shettles method (same thing as what is described it Taking Charge of Your Fertility), it was a perfect "girl attempt" with the exception of that they recommend skipping the jaccuzi but do say that being exposed to higher temps kills off the boy swimmers.
When DS #1 was a year old we decided we shouldn't waste time trying for baby #2 since baby #1 didn't come easily so we went back to the RE. They decided to try me on high dose Clomid but no injectables to start with. We decided we try on our own with just meds and monitoring for at least 6 months before moving on to IUI if need be. My cousin had given me her copy of the How to Choose the Sex of Your Child book and I read it. We decided we'd give a girl attempt a shot but knew that if it ended up being a boy, we would not be disappointed in the least bit. DS #2 was another classic girl attempt....once again...all boy! We ended up pregnant with him faster than we expected and they are just under 2 years apart. I love that they are both boys.
Makes life easier with them this close...they are interested in the same things and they are BEST BUDS. I love hearing them playing in their room and telling each other "you are my best friend" and "I love you!"
We're pregnant again with baby #3. This one was a surprise. We've used infertility as our method of birth control for years and this was just proof it's not the most effective method.
Seriously...10 years no birth control, we have 2 kids that both required "help" one with the max dose of Clomid plus an injectable med and one with the max dose of Clomid...and one surprise pregnancy. Anyway, I'd since had 2 or 3 people tell me that they had heard that a more effective method for trying for a girl was to time for around 12 -18 hours AFTER ovulation. Nothing for more than 3 days before but waiting till 12 hours after. With this baby, DH was out of town for a few weeks coming home for a weekend in between so it was a sort of one shot deal that this one happened. I don't chart my temperature anymore but I do make note of fertility signs (not on paper, just in my head) and this should have been more than 24 after all of my signs peaked. Since I was going by the same signs this method recommends you use, this would have been a girl attempt by that. We just had a sonogram a few weeks ago and we're about 90% sure that this is baby boy #3 for our family.
DH and I both said yeah it would have been nice to have a daughter but neither of us feel like anything is MISSING from our life because we don't have a daughter. We had thought we were done before this baby (so much so that DH had an appointment for a vasectomy scheduled at the time but it was for about 3 weeks after I ended up pregnant!). Nothing changes with this one...still nothing missing in my life. I adore my sons and will adore this one too. I know boys...I've got more than enough Thomas the Tank Engine stuff, Tonka truck stuff etc. so we're all set! The boys are just thrilled to be having a little brother too.
Nothing is perfect, I know as many people that this method did NOT work for as people that it did and will swear by it. The OB who delivered DS #2 said in her opinion, it changes the odds from 50/50 to maybe 60/40 on a good day. As long as you are wanting A BABY and not a son or a daughter and will not be devastated to get the "wrong" gender, I don't see anything wrong with it. If you feel like your life will just be ruined by not getting the gender you hope for, this method isn't something to sink all your hopes in to but there isn't any HARM in it either.
Good luck! I hope you are able to have a happy, healthy pregnancy followed by a happy healthy baby!
It's a crapshoot! 
DD was born to our surprise and delight!! I cant go through all the b/c methods we were using, but we were!! (there's a 10 year gap)
