Ok, I believe I had a chemical pregnancy because my period, aka AF (aunt flo), was late, I had pregnancy symptoms, and I had a faint positive pregnancy test. Remember everyone, a faint positive is still a positive. And I truly felt pregnant, different than I've felt any other month. Coincidentally, I had my annual obgyn appointment during this time, but it was too early to take a pregnancy test. My doc explained I needed to wait 14 days after ovulation to take a pregnancy test. Also, for the first time in my life I spotted after the Pap smear, which is another sign of pregnancy. So, I waited several more days and got my faint positive, just as the doctor had said. Several days later I got AF - the pregnancy didn't stick. It was disappointing, but it didn't really upset me that much because I knew chemical pregnancies were very common, it's just that most women don't know they are happening.This is when I began to realize something was wrong, and not just chemical pregnancy wrong, but more than that. My cycles have always been around 36 days. This was the first time I figured out when I ovulated, and I ovulated on CD (cycle day) 28. I began to research this stuff on the internet, and learned that ovulation after CD20 is considered "late ovulation." I also learned that being vegetarian will give you longer cycles and make you ovulate later. Most distressing of all, I realized that my luteal phase was too short to sustain a pregnancy. The luteal phase is the part of a woman's cycle from ovulation until her next period. Anything 10 days or less is considered bad for ttc, ideally you want around 14 days. Mine was 8 days that cycle. There's even a term, "luteal phase defect."
