Should I seek help?

[josephine25]

Should I be concerned? I am trying to get pregnant. I came off the pill on 23rd September 2013, after being on it for 10 years. I had my usual period on 28th September, which lasted 5 days. Then I didnt get a natural period until 23rd November 2013. Which meant my first cycle was 56 days, the period lasted 5 days. My next cycles were 42 days, 37 days, 43 days, all lasting 5 days. We started trying at the beginning of March 2014, after my 37 day cycle. I am now on day 50 of a cycle, obviously no period and also a negative pregnancy test. Should I see a doctor? I keep reading that those with cycles over 37 days should see a doctor, however, although my cycles seem long, they did seem regular around the 40 day mark, but now it 50 days and it doesn't seem like I'm pregnant.
