In the past, I could count on my period like clock work. I had a 28 day cycle that last for 4 to 5 days. For some reason the past 3 months, I've been irregular. In March, I started on Sunday the 29th (which was normal). In April I started on Monday the 30th, May on Monday the 27th and June I started on Thursday the 25th. At first I thought, maybe my cycle was extending to 29 instead of 28 days but this month I was 2 days late. This time around, my cramps were more intense than normal, I've been really bloated and my period only lasted for about 3 days. It was kind of heavy the first day and then last two it was light. Prior to my period, I was also having touble with bowel movements, I was passing them only every other day or so. I was and still and very bloated. There hasn't been any changes that would effect my cycle in the past few months; I haven't been on birth control in over a year, I haven't been stressed, there hasn't been any changes in my diet and I haven't been around any new women, so I guess my questions are:

Is there any way, other than oral contraceptives, to regulate my period?
Why might this change have happened?
How can I calculate my ovulation? (my husband and I are trying to have a baby)
Is it possible I may be pregnant?
Thanks!
