Irregular Cycle?

Hi! So, I was on birth control for 9 years. I got off the Nuva Ring in April 2015 (7 months ago) b/c my husband and I want to have a baby. My cycles so far have been: 28 days, 43 days, 30 days, 30 days, 33 days, and currently on day 49 with no period. I've taken a pregnancy test and an Ovulation predictor test and both were negative.

I have taken an Ovulation Predictor Test (5 months ago now and got a + on CD 15). But only that time have I used one (and this week I tried one just for fun, lol).

I just wanted to know if this is common or if this has happened to anybody else before?

I'm 29 years old, at a healthy BMI, work out 3 to 4 times a week for an hour each time, try to eat healthy, and meditate/relax as much as I can.

Any advice? I'm gonna try and schedule an appointment with a doctor this week. Just wanted to reach out to others to get some advice! :)

Thanks!
