Hello ladies! My cycle has been shorter lately and I'm wondering if any of you have had this happen to them. I just need a little advice before I get to the doctor.

I usually have a cycle that is 25-27 days and my period last for 4 days. It all started on,

Sept. 30-3 then October 17-20 and now Nov. 3- 6th. I don't know why they've gotten shorter.

I do have mixed connective tissue disorder but it has never thrown off my cycle. I'm not on medication. I was taking vitamin B, D and biotin from August to the beginning of October.

Has anyone experienced getting shorter cycles? Oh I'm 34 by the way, no children. I'm starting to get concerned. Thanks in advance ladies!!
