Menstrual question ladies

Hi ladies,
I had my RNY on January 26th. and my last menstrual was on the 13th. of the same month.  Needless to say that I have not heard from aunt flow since.  (No I am not prego and I know that for sure).  I'm asking because I don't want any "accidents" it's impossible to gauge my ovulation when it's so out of wack! 
Is this common or should I see my GYN because I'm pretty regular otherwise.

Thanks in advance ladies

Everything goes out of whack with surgery, but I would suggest you make an appointment with your GYN. Better safe than sorry.

Take care,

Chagrin

Thank you Chargin21.

Ditto.  Your body just underwent a major change and is in shock so to speak.  Never hurts to be proactive though.  Call the GYN.

Thanks Hershey.  I appreciate the feedback.
