My menses returned 3mpp...and has been regular since. But this month its delayed.. Will menses be regular or irregular once it is back? I am pumping and latching..past 1 week supply seem to drop...not sure is it menses coming or due to i drop 1 pump..

It is quite difficult to tell if your period will be regular or not but I would think that it should be since you mentioned that it has been regular. But as with all cycles, it could be affected by factors such as stress. Fluctuations in supply may be due to period. Some of my friends notice a dip prior to or during their period. Is there any chance that you may be pregnant? Perhaps you can take a pregnancy test if your period has been delayed by one week.
