Questionsssssss

So earlier this month AF was 2 days late.. then it was like a normal (med-heavy) period for ONLY 2 days, it’s always on time, and usually about 4-5 days long. I have carried on with life as usual, I have a couple of alcoholic drinks almost daily.. I mentioned to my mom and she said it could be a sign of pregnancy, she knows my husband and I want a baby. But my question is, has anyone else had this issue of late period and being shorter than usual? And did next month go back to normal?
