Question for the ladies?!?!?

So I'm about 3 1/2 months post op and the past couple of days I have been spotting. My period is not due for a week. I thought that there was a chance my period would be a bit messed up by all this surgery and weight loss but didn't think it would be this late out. Has anyone been previously regular and had bleeding at unexpected times? I am not on a birth control pill so it would have nothing to do with that. Thanks for your help!!!

When I have surgery I always get messed up for the 1st month or 2 if this keep up I would call your doctor but,  I had the same kind of problem with 2 surgery of mine.  Good luck take care
