It could be something else.......is it normal for you to miss periods? If so, do you also have a hard time losing weight? I ask because along with fertility issues these are symptoms of PCOS (polycystic ovarian syndrome). This can develope at anytime and 10% of women have this and may not even know. I am one of those women, so if you have other symptoms, contact me and I can help you. I can point you in the right direction were doctors are concerned (I was misdiagnosed for 10 years!).
All the best to you!!
