Just wondering... (Concerned and having trouble TTC) *For women with infertility *

I was wondering what where your first symptoms I guess? And what made you go get checked out? Also how were your periods ? Mine is every other month and it starts out spotting for 3 days then its light and then heavy for one day then the rest light then it goes back to spotting brown for a few days. And we've been TTC for a year now but no luck.
