Hi , My period ended on the 3rd of January and I had unprotected sex on the 19th and 20th of January but he did not cum. I took the morning after pill on the 21st just to be safe. And on the 23rd I have been getting a small amount of brownish discharge - is this because of the pill or does it mean my period is almost here ? I'm stressing out slightly as I don't want to be pregnant , please help.
