Quoting MiSS JDM (ttc#2):" omg really so giving up is pretty much the key to getting pregnant lol because that month that i tested ... [snip!] ... there just going to be negative and he told me to take one anyways and bam 2 very dark lines popped up lol i was so shocked"
You should ask your doctor for provera to get AF to start, it might help you ovulate too. And you should get hormone levels checked to make sure everything is good once you do get pregnant. You might need to be on progesterone.
I didn't have AF for awhile before my first son. I went like 2- 3 months all the time without it. Then when I was getting closer to TTC I got worried and took provera and metformin. My cycles became regular and I got pregnant 3 months after on the first try. You aren't going to get pregnant very easily until your cycles get better. Maybe you aren't ovulating either.
