Hi
I myself struggled with the same issue and I couldn't afford the high prices and I really didn't want to put my body through all the medicine with hormones.
I was recommend Lady-Comp baby fertility monitor by a friend from a Germany and she was successful with it. So I tried it and became pregnant on the 3rd month and it was the best feeling ever when it indicated that I was pregnant. Its 2200 Aed so a lot more affordable than going to a clinic here in Dubai. You can also use it as a natural contraception afterwards, which I am doing now to plan for the next baby. Here is the link for you to read more about it http://www.lady-comp.ae
Good luck!
