so frustrated

There is absolutely no consistency with my cycles it seems. It's just a mess. Now I'm on day 47 and technically late. I used to be 37 days and then I don't know what happened but things aren't on track anymore. I haven't tested because it's usually a disappointment. Just frustrated. My doctor has done test after test and everything is "normal". But yet here I am almost 2 years later, haven't conceived once and my cycle is messed up. 😞
