Confused????

I had my son back in September 2017&& then a tubal November 17th 2017.... my periods have been coming on the 23rd or 24th of every month.... Expect this month.. I haven’t started so that makes me 6 days late..... I know the chance of pregnancy is really slim.. but I was just wondering if anyone else has had this happen.... had a tubal&& your periods all of a sudden get messed up.? Or has anyone ever got pregnant after having a tubal done.? I’m just confused..
