Hi A.,
have you used Toni Wexler's book, "Taking Charge of Your Fertility"? It is an excellent book, and may help you to chart your cycles so you can figure out what is going on.
Yes, it is easier for some than for others, who knows why. Just remember that MANY many women need help to become pregnant. If you do not become pregnant after one year of trying, you can go to a fertility specialist to see if they can help you.
Also, some people swear by acupuncture (I have done it, and the needles don't hurt - it is actually very relaxing).
Personally, we had a terrible time getting pregnant the first time (lost my first baby at 10 weeks), then couldn't get pregnant for over a year, tried all kinds of things, then as we were going for IVF, discovered I had thyroid cancer. Had to have surgery and take time to heal from that. Then, got pregnant easily - twice in the next 6t months, but lost both of those around 5 -6 weeks. So - we went back to IVF and finally after two cycles, conceived our daughter (who is now 2 1/2). This time, when we wanted to try again, we just went right to IVF, and it worked the first time.
So - you never know who will need help and who won't. Just remember, so many women need help getting pregnant most people just keep quiet about it because it can feel so personal. So many people have to really try and try.
Use the book and acupuncture first, and good luck to you!
