Was It Normal Menstruation or a Chemical Pregnancy?

QUESTION

Dear Midwife,
My cycles are regular 27 - 29 days..

Only two of my cycles lasted for 30days. Both the times we had bed around CD 15.. ie around the time of ovulation.

These cycles i had abdominal cramps either left or right.. and belly button pain, which is unusual for me. I never had these as PMS. So I was sure I was pregnant.. but then AF showed up two days late.
I think I have had a chemical pregnancy.. how do I make sure its not a chemical if similar things happen the next time?

My second question is this:

Also menstruation bleeding always lasts only 2 days..so is it possible that I am never ovulating?

ANSWER

First, if you are at all late with your period, you should take a pregnancy test. There is no other way to know if you were ever pregnant, as there are lots of things that can delay a period or change its consistency. I am not doubting your analysis, I'm just saying that we don't know for sure, and never will know what has happened in the past, since the test wasn't done. There is no way to prevent a blighted ovum/chemical pregnancy other than avoiding things known to hurt the baby like alcohol, drugs, certain prescriptions, etc.

Second, you can tell if you are ovulating with an ovulation predictor kit. You can also chart your temperatures. The length of your period usually doesn't affect your chances of pregnancy. If you have been trying for over a year, then it is time to see someone who knows about infertility and can help you.
