What Causes Irregular Periods?

I used to have a 28 day cycle then it changed to a 21 day cycle for a couple of months. It then went back to a 28 day cycle. I recently got pregnant. Were the days of my ovulation back to around the 14th day mark with my 28 day cycle or would they still have been around the 7th day from my previous 21 day cycles?

Hello dear, I really appreciate your concern. Day of ovulation can be predicted on the basis of duration of menstrual cycle but it is a crude method of prediction. You can not be so certain about it. For these purpose you can go for hormone testing.
Hope my answer has solved your query. Take Care.
Thank you.
