My husband and I have been trying since September 2015

My husband and I have been trying since September 2015. I was on birth control for 8 years. I had really irregular periods. My first period didn't come for 50 days. My second cycle was 36. I used clear blue digital ovulation predictors and that came back peak on December 5 along with other ovulation symptoms. I did not get a positive pregnancy test until January 8. I thought I was going to have another 50 day cycle when really I was pregnant! I tested for 2 weeks starting Decemeber 19th -January 2. All of them came back negative. It just took my body a little longer to get a positive!
