Hi. My period was due on the 19th however it only came on the 22nd. On the 21st I noticed pinkish brown in colour and it was light, but on the 22nd my period was heavy. It lasted 2days. Is that normal?

? We don't know, is it normal ? Your normal, her normal, my wife's normal is all different.

First three days is not really late, periods very all the time for more than that.
Next they may often be light and then heavy the next month.

So your normal is not the same as anyone else often.

I assume you are thinking pregnancy ? Are you sexually active ?

If that is what you are thinking, wait two weeks after period and try a pregnancy test with first urine of morning.

If not, just wait till next month and see if it is back to "YOUR" normal.
